Conformational Reorganization Of Hyperbranched And Linear Polymers And Functionalized Porous Polymer Films
(2014-04-22)The main focus of the research work presented in the thesis is the understanding of structural and conformational reorganizations in hyperbranched and linear polymers. The thesis includes three different investigations: ... -
Controlling Conformation of Macromolecules by Immiscibility Driven Self-Segregation
(2018-05-09)Controlling conformation of macromolecules, both in solution and solid state, has remained an exciting challenge till date as it confronts the entropy driven random coil conformation. Folded forms of biomacromolecules, ... -
Controlling Conformation Of Macromolecules Using Non-Covalent Interaction And Micellization Behaviour Of Isomeric Phenyl Bearing Cationic Surfactants
(2013-06-24)This thesis contains investigations in two different areas, described under six chapters. Chapter 1 contains a broad introduction to the area of foldamers, while Chapters 2, 3, 4, and 5 deal with various novel classes of ... -
Controlling The Conformation Of Polymers In Solution And Synthesis And Characterization Of 'Clickable' Polyesters
(2013-01-11)The thesis constitutes investigations from two distinct areas of research. One part deals with controlling and modulating the conformation of linear polymer in solution. Folding of a polymer chain has been achieved by ... -
Exploring New Designs of Amphiphilic Graft Copolymers and Forays into 2D Polymers
Amphiphilic polymers, wherein two or more immiscible polymeric segments are connected covalently, form an interesting class of macromolecules that can self-assemble in block selective solvents as well as in bulk, to exhibit ... -
Functional Derivatives Of MEHPPV Using The Dithiocarbamate Precursor Route
(2009-04-02)Emissive conjugated polymers, namely PPV, PPP, polyfluorenes, etc, have gained considerable attention in recent times, specifically because of their potential application in the fields of PLED’s, displays, FET’s and ... -
Functional Hyperbranched Polyethers Via Melt-Transetherification Polymerization
(2010-04-12)Dendrimers are highly branched macromolecules which are prepared by a stepwise procedure. The presence of a well-defined core, discrete generations and a large number of terminal groups in dendrimers make them structurally ... -
Hyperbranched Polyacetals and Polydithioacetals
(2018-04-23)Dendrimers are a class of perfectly branched symmetric monodisperse macromolecules, which are synthesized using a stepwise procedure. Due to their highly symmetric structure, they possess a definite core, discrete generations ... -
Itaconate Based Novel Amphiphilic Polymer Architectures
Amphiphiles are natural or synthetic molecules consisting of hydrophilic polar head group and hydrophobic non-polar hydrocarbon tail. Beyond a certain concentration, known as critical micellar concentration (CMC), amphiphilic ... -
Itaconate-based Periodically Grafted Polyesters
(2017-12-03)Block copolymers can self-assemble into a variety of periodic nanostructures and therefore, are promising candidates for a diverse range of applications. While self-assembly of block copolymers has been widely studied and ... -
Molecularly Imprinted Polymers Based On Fluorescent And Template Binding Cross-Linker
(2013-05-23)The synthesis of materials with molecular recognition properties has become a topic of great technological and scientific interest. Molecular imprinting is one of the most effective strategies in preparing highly selective ... -
Polymerizable Porogen – Direct generation of internally functionalized porous polymers
Bicontinuous functional porous polymers are desirable in terms of pore accessibility, particularly for applications in templating, chromatographic separation, and catalysis. Bicontinuous morphologies can be obtained by ... -
