Abstract (sommario):

This thesis deals with wider application and implications of the hydrogen bond in crystal engineering studies and beyond; in addition, it also highlights the Cambridge Structural Database (CSD) as the potential knowledge-mine for inorganic chemists. The content of this thesis covers mainly three areas, viz, the role of hydrogen bonding in crystal engineering studies, the bridging between mainstream crystal engineering studies and solvates via hydrogen bond, and CSD studies on metal coordination spheres. Chapter 2 deals with crystal structure prediction through understanding the driving forces

Abstract (sommario):

OH-stretching spectra of various vapour phase species were recorded to investigate hydrogen bonding. The species studied include 1,2-ethanediol, 1,3-propanediol, 1,4-butanediol, acetylacetone, hexafluoroacetylacetone and the complex formed in the heterogeneous mixture of methanol and trimethylamine. The spectra range from the infrared, near infrared to visible wavelengths. The main focus of this study is in the near infrared region, in which the OH-stretching overtones are dominant. The near infrared and visible spectrum of formic acid has been recorded to investigate coupling across bonds,

Abstract (sommario):

When multiple hydrogen bonds lie in-plane and parallel to each other in close proximity, they experience additional positive or negative secondary electrostatic interactions. When a pair of molecules are arranged such that every hydrogen bond acceptor is on one molecule and every hydrogen bond donor is on another, the positive secondary electrostatic interactions are maximised, and thus the association constant of the complex is enhanced. This thesis will present the development of a family of quadruple hydrogen bonded complexes containing only positive secondary interactions, which confers un

Abstract (sommario):

Intra- and inter-molecular hydrogen bonding greatly affects both physical and chemical properties for a wide variety of important molecules. This study focuses on intramolecular hydrogen bonding in polyhydroxy-1 ,4-naphthoquinones. The little known "bond counting rule", dictates that the global minimum will be comprised of a maximum number of highly stabilizing interactions. Hydrogen bonding was chosen for this work as the energy of the bond is typically 20-40 kJ mol-1, which is larger than computational error, allowing statistically significant energy differences between conformers to be dete

Abstract (sommario):

Hydrogen bonds are directional, non-covalent interactions between hydrogen and electronegative atoms. Although generally weak, these interactions are critical to the stability of many biological systems including proteins and DNA. This dissertation explores small molecules in which an intramolecular hydrogen bond is the key determinant of conformation. Chapter 1 introduces the protein Grb2 SH3C, details its role in cancer signalling, and delineates the idea of peptidomimetics—small molecules which are functionalized to mimic the structure of a peptide and disrupt protein-protein interactions.

Abstract (sommario):

Non-covalent interactions are fundamental to molecular recognition processes that underpin the structure and function of chemical and biological systems. Their study is often difficult due to the interplay of multiple interactions and solvent effects common in complex systems. Herein, chapter one provides some general background on the area before presenting a literature review of key, contemporary developments on the use of folding molecules for the quantification of non-covalent interactions. Chapter two investigates the magnitude and extent of energetic cooperativity in H-bond chains. Utili

Abstract (sommario):

The dynamic characteristics of hydrogen and ionic bonding contributes to the reversible properties of acrylic polymers, opening new avenues for designing materials with mechanical strength and processability. These non-covalent interactions function as physical crosslinks, which provide enhanced structural and mechanical integrity to acrylic block copolymers. The strong hydrogen bonding or ionic interaction also directs self-assembly to hierarchical microstructures, which enables many applications including thermoplastic elastomers and energy storage devices.

Abstract (sommario):

This work describes the design and synthesis of a set of four organic molecules that are intended to hydrogen-bond to each other in a pairwise manner. The four hydrogen-bonding units, termed ‘A’, ‘B’, ‘C’ and ‘D’, when placed in solution together, are designed so that A binds only to B, and C binds only to D. Each unit does not bind to itself, nor to either of the other two units to which binding is not intended. For example, A binds to B, but not to A, C, or D. Each unit contains an array of four hydrogen-bonds for strong binding to its partner, is designed to be as rigid as possible, as non-

Using aqueous solubility data, from a number of sources, for a set of subsituted aromatic compounds, group or q values are derived. Group values have been generated for a number of substituents, none have included hydrogen bonding groups (Myrdal et al., 1992,1993). Q values are related to activity co

The complexation of thiolated nucleosides and nucleobases with a range of group 11 metal ions (Au(I), Ag(I), Cu(I/II), was observed to lead to the formation of hydrogels by simple inversion tests. Atomic force and electron microscopy of the xerogels showed, in many cases, the presence of fibres with lengths in the micrometre range and above; this provided evidence for the formation of coordination polymers. This thesis is concerned with the preparation, characterisation and investigation of the physical properties, mainly photoluminescence and conductivity, of these coordination polymers. 2’-D

Abstract (sommario):

Supramolecular polymers represent a family of polymeric materials that are held together with dynamic, noncovalent interactions. In contrast to conventional functional polymers that usually have high melt-viscosity due to their covalent nature and chain entanglement, supramolecular polymers combine excellent physical properties with low melt-viscosity, allowing for less energy-intensive processability and recyclability. Dynamic bonding with multiple binding sites, such as multiple hydrogen bonding or multiple ionic bonding, exhibits much stronger binding strength compared to the counterparts c
