Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 2008.<br>Includes bibliographical references.<br>There is significant interest from both the academic and industrial communities for understanding and controlling the self-assembly behavior of complex macromolecular systems and has been an active area of research in recent years. Such systems can be designed to result in a wide range of nanoscale morphologies and greater functionality can be introduced with increasing complexity.This thesis focuses on the synthesis and characterization of a clas

Abstract:

Posed with the challenge of engineering and characterising nanoscaled objects, this thesis reports on the development of self assembling (cyclic peptide)-polymer conjugates as a versatile supramolecular route to complex nanostructures. A variety of conjugates was synthesised by microwave assisted copper(i)-catalysed azide-alkyne cycloaddition, covalently coupling alt(d,l) α cyclic peptides with synthetic polymers. The product of self assembly was then characterised in solution by small angle neutron scattering. Manipulating the grafted polymer and the chemical functionality of the peptide infl

Abstract:

New ABC triblock copolymers were synthesized by controlled free-radical polymerization via Reversible Addition-Fragmentation chain Transfer (RAFT). Compared to amphiphilic diblock copolymers, the prepared materials formed more complex self-assembled structures in water due to three different functional units. Two strategies were followed: The first approach relied on double-thermoresponsive triblock copolymers exhibiting Lower Critical Solution Temperature (LCST) behavior in water. While the first phase transition triggers the self-assembly of triblock copolymers upon heating, the second one a

This thesis reports a novel route to molecular self-assembly based on simple acid-base hydrolytic chemistry involving the reactions of aminosilanes with organic species containing acidic protons. From detailed solution chemistry of trimethyl-, trimethoxy-, and triphenyl-chloro/amino-silanes, two general processes have been developed for the self-assembly of long alkyl chain terminated alcohols, thiols, and carboxylic acids on inorganic oxide surfaces i.e., glass, quartz and single crystal silicon. The first method involves three successive reactions with the surface moieties where the initiall

Abstract:

DNA nanotechnology is a rapidly developing field that creates nanoscale devices from DNA, which enables novel interfaces with biological material. Their therapeutic use is envisioned and applications in other areas of basic science have already been found. These devices function at physiological conditions and, owing to their molecular scale, are subject to thermal fluctuations during both preparation and operation of the device. Troubleshooting a failed device is often difficult and we develop models to characterise two separate devices: DNA walkers and DNA origami. Our framework is that of c

Abstract:

This communication reports a unique ultra-large sheet formation through hierarchical self-assembly of a rod–coil graft copolymer containing a rigid polyphenylene backbone and flexible poly(ethylene oxide) (PEO) side chains. The hierarchical self-assembly process involved a distinctive morphological transition of 1D helical to 2D superstructures. The graft copolymer offers a new chance for the challenging bottom-up fabrication of ultra-large self-assembled nanosheets in solution, as well as a novel system for fundamental studies on 2D self-assembly of polymers.

Synthesis of well defined polymers containing metal complexes in the side chain is achieved either by the direct or the indirect approach. The direct approach utilizes NMP and RAFT to copolymerize 2,2':6',2''-terpyridine ligand (terpy) functionalized styrene (Styterpy) monomer in combination with other comonomers. The indirect approach produced polymers using ATRP technique containing either terpy or [Ru(terpy)2]2+ metal complex in the side chain. The indirect approach is considered the best method to obtain terpy or metal complex containing polymers in the side chain. Luminescence block-rando

From Stille coupling reactions, we synthesized four series of donor-acceptor alternating conducting copolymers.
