Abstract:
Pillararenes trimer with particularly designed structural geometry and excellent capacity of recognizing guest molecules is a very efficient and attractive building block for the fabrication of advanced self-assembled materials. Pillararenes trimers could be prepared via both covalent and noncovalent bonds. The classic organic synthesis reactions such as click reaction, palladium-catalyzed coupling reaction, amidation, esterification, and aminolysis are employed to build covalent bonds and integrate three pieces of pillararenes subunits together into the “star-shaped” trimers and linear foldamers. Alternatively, pillararenes trimers could also be assembled in the form of host-guest inclusions and mechanically interlocked molecules via noncovalent interactions, and during those procedures, pillararenes units contribute the cavity for recognizing guest molecules and act as a “wheel” subunit, respectively. By fully utilizing the driving forces such as host-guest interactions, charge transfer, hydrophobic, hydrogen bonding, and C–H…π and π–π stacking interactions, pillararenes trimers-based supramolecular self-assemblies provide a possibility in the construction of multi-dimensional materials such as vesicular and tubular aggregates, layered networks, as well as frameworks. Interestingly, those assembled materials exhibit interesting external stimuli responsiveness to e.g., variable concentrations, changed pH values, different temperature, as well as the addition/removal of competition guests and ions. Thus, they could further be used for diverse applications such as detection, sorption, and separation of significant multi-analytes including metal cations, anions, and amino acids.

Abstract:
The construction of a porphyrin array by a stepwise, hierarchical self-assembly process is described. Four molecular clip host molecules are complexed, in a solid state self-assembly process, to one porphyrin guest molecule. When dissolved in chloroform, the 4:1 host-guest complexes spontaneously self-assemble into an array in which the porphyrins are organized in a cofacial stack. The ensemble is stabilized by a combination of π-π interactions between the porphyrins and between the aromatic surfaces of the host molecules.

Abstract:
Fabricating well-defined and stable nanoparticle crystals in a controlled fashion receives growing attention in nanotechnology. The order and packing symmetry within a nanoparticle crystal is of utmost importance for the development of materials with unique optical and electronic properties. To generate stable and ordered 3D nanoparticle structures, nanotechnology is combined with supramolecular chemistry to control the self-assembly of 2D and 3D receptor-functionalized nanoparticles. This review focuses on the use of molecular recognition chemistry to establish stable, ordered, and functional nanoparticle structures. The host–guest complexation of β-cyclodextrin (CD) and its guest molecules (e.g., adamantane and ferrocene) are applied to assist the nanoparticle assembly. Direct adsorption of supramolecular guest- and host-functionalized nanoparticles onto (patterned) CD self-assembled monolayers (SAMs) occurs via multivalent host–guest interactions and layer-by-layer (LbL) assembly. The reversibility and fine-tuning of the nanoparticle-surface binding strength in this supramolecular assembly scheme are the control parameters in the process. Furthermore, the supramolecular nanoparticle assembly has been integrated with top-down nanofabrication schemes to generate stable and ordered 3D nanoparticle structures, with controlled geometries and sizes, on surfaces, other interfaces, and as free-standing structures.

Full text
Abstract:
This thesis is primarily concerned with the synthesis and characterisation of heterometallic polynuclear coordination structures, but also contains host-guest studies of mononuclear complexes. Chapter One consists of an introduction to self-assembly and supramolecular chemistry. Recent examples of coordination cages are given along with previous work from the Ward group. An introduction to recent efforts in the field of heterometallic supramolecular chemistry is also given. Chapter Two describes the use of a series of mononuclear Ru(II) complexes to act as models for the vertices of coordination cages. A simple and general synthetic procedure is described which will allow access to a wide range of substituted analogues of [Ru(LH)3]2+ as their pure fac and mer isomers. It has been shown that the fac-[RuL3]2+ complexes bind to isoquinoline N-oxide more strongly than the mer isomer, but much less strongly than the complete cage complex due to the presence of competing anions, which are excluded from the cage cavity. Chapter Three describes the formation of a series of heteronuclear coordination cages from inert and labile subcomponents. The synthesis of a range of mononuclear [RuL2]2+ and [RuL3]2+ complexes as either a mixture of mer and fac isomers or pure fac is discussed, followed by the self-assembly of two heterometallic cubes [Ru4Cd4(L1,5-nap)12]16+ and [Ru4Co4(Lm-Ph)12]16+, a [Ru4Cd12(Lp-Ph)12(L1,4-nap)12]32+ cage, the adamantoid cage [{Ru(Lp-Ph)3}4Ag6]14+, and the trinuclear [{Ru(Lo-Ph)2}2Ag]5+. Chapter Four describes the syntheses and characterisation of a family of asymmetric ligands based upon pyrazolyl-pyridine and catecholamide binding moeties connected by aromatic spacers. The synthesis and structural determination of a tetrameric hetero-octanuclear cyclic helicate [Ti4Zn4(L1,3)8(μ-OMe)8] with the ligand H2L1,3 is described. Chapter Five describes the efforts towards functionalising the exterior of M8L12 cages. The synthesis of the aniline functionalised ligand Lan is discussed, which self-assembles with Co(II) to form a [Co8(Lan)12]16+ cube. Functionalising the ligand with ferrocene to form LFc results in the self-assembly process with Co(II) now forming a [Co6(LFc)9]12+ structure.

Abstract:
Supramolecular cage complexes are of great interest, not only for their structural elegance, but also for their applications. Chapter 1 describes a collection of the many types of cage complexes based on three-dimensional polyhedral shapes and the host-guest chemistry that some cages complexes, enabled by their central cavities, are able to exhibit as they encapsulate small molecules. This thesis contains a number of studies, starting with an investigation into the host-guest chemistry of the tetrahedral cage complex [M4(Lbip)6⊃(BF4)](BF4)7 [where M = Co(II) or Cd(II)]. Anion exchange is able to take place in these complexes, replacing tetrafluoroborate counterions for 1-naphthyl sulfonate or tetraphenylborate molecules. This is summarised in Chapter 2. Chapter 3 details three experiments that look into the stability and the self-assembly process of tetrahedral cage complexes in solution. Two experiments involve the use of electrospray mass spectrometry, one to monitor the exchange of ligands between two tetrahedral cages, and the other to monitor the exchange of metal(II) ions between two isostructural cages. The third study follows the self-assembly of a tetrahedral cage by employing UV/vis spectroscopic titrations and uses equilibrium-restricted factor analysis to model the additive factors in the data as definite chemical species. Chapters 4 and 6 describe new ligands and modifications to ligands by altering the pyrazolyl-pyridine binding units. It has been discovered that using pyrazine in place of pyridine (Chapter 4) on the ligands has a dramatic effect on the construction of the final product. The encapsulation of neutral molecules by the cubic cage complex [Co8(L1,5-nap)12](BF4)16 is investigated in Chapter 5 and it has been discovered that coumarin binds to the internal cavity of the cage. The paramagnetic Co(II) metal centres cause the signals of the cage protons in the 1H NMR spectrum to be spread over a wide range (± 100 ppm). This makes it easy to see the guest signals and to identify any changes due to host-guest binding.

Abstract:
Various technologies depend on interfacial events that are influenced by various molecular interactions at a solid-liquid interface. The functionality of a surface plays an important role in many applications such as catalysis, sensing, and bio-compatibility, which can benefit from distinctive chemical and physical surface properties. To create tailor-made functional surfaces, surface host-guest assemblies based on Langmuir-Blodgett and self-assembly technique have been employed as a model system as they may offer the potential ability to regenerate surface properties via intercalation of various functional guest molecules. This thesis ranges over the development and characterization of host-guest assemblies and their feasibilities for the regeneration of surface properties via intercalation of functional guests. In our work, 3-dimensional host structures with cavities are constructed on a targeted solid substrate using Langmuir-Blodgett and self-assembly techniques. In particular, by adopting the fundamental concept of host-guest interaction in supramolecular chemistry, we expect that structurally homologous guest molecules where functional groups are anchored can be intercalated into the cavities between hydrophobe arrays at the liquid-solid interface from solution under well-controlled conditions. This approach offers the potential of separating the functional of the monolayer from the inherent structure of the host. The first part of this thesis details two-dimensional host-guest assemblies consisting of guanidinium (G), octadecylsulfonate (S) and various functional alkane guests at the air-aqueous interface and following deposition onto solid substrates via the Langmuir-Blodgett technique. In particular, we evaluated the stability of the host-guest assemblies and the feasibility of exchanging molecular guests under exposure to various organic solvent environments. Analysis of X-ray reflectivity measurements of the thin films showed that good stability of the host-guest assembly could not be achieved due to weak interactions between the host monoalyer and the solid surface. In addition, no evidence of intercalation of guest molecules into guest-free host-cavities was observed. The second part of this thesis discusses the effective methodologies to prepare low-density self-assembled monolayers (LDSAMs) with cavities on silicon substrates. We employed a step-wise reaction based on hydrolytic or silane chemistry: integral spacer molecules such as anthracene-derivatives were anchored to the Si substrate and then long alkane chains were appended to the spacer molecules. The results showed that LDSAMs using an anthryl spacer are attached at the SAM/Si interface via a Si-O-C linkage, and the films do not exhibit a densely packed monolayer quality as would be expected for a non-sterically hindered alkyltrichlorosilane on Si. Thus, the resulting LDSAMs (with cavities) may be capable of accommodating other guest molecules with hydrocarbon chains through intercalation in order to form host-guest assemblies. The third part of this thesis demonstrates the ability of LDSAMs to produce functional surfaces via the intercalation of various functional guest molecules. Self-assembled monolayers of (10-octadecyl)-9-anthracenethiol (host-SAMs) on Au substrates were prepared. Quartz crystal microbalance with dissipation (QCM-D) measurements was used to demonstrate the capacity of LDSAMs to confine guest molecules in the cavities and to probe the structural changes of the host-guest assembly during guest intercalation from ethanol solution. X-ray photoelectron spectroscopy (XPS) measurements were then used to probe host-guest monolayers formed by immersing the host monolayer in solutions in a variety of other solvents. A combined study of QCM-D and XPS showed that guest molecules were intercalated into host-cavities. The reversibility of the intercalation process allows a guest already situated in a host-cavity to be replaced with second guest under well-regulated solvent conditions.<br>Ph. D.

Abstract:
This article focuses on the use of molecular films as building blocks for nanolithography. More specifically, it reviews efforts aimed at utilizing organic molecular assemblies in overcoming the limitations of lithography, including self-patterning and directed patterning. It considers the methods of patterning self-assembled organic monolayer films through soft-lithographic methods such as microcontact printing and nanoimprint lithography, through direct ‘write’ or ‘machine’ processes with a nanometer-sized tip and through exposure to electron or photon beams. It also discusses efforts to pattern the organic assemblies via the physicochemical self-assembling interactions, including patterning via phase separation of chemically different molecules and insertion of guest adsorbates into host matrices. Furthermore, it examines the efforts that have been made to couple patterned molecular assemblies with inorganic thin-film growth methods to form spatially constrained, three-dimensional thin films. Finally, it describes a hybrid self-assembly/conventional lithography (i.e. molecular rulers) approach to forming nanostructures.
