Two new azo organic molecules Azo-OCH 3 and Azo-Br were synthesized by using electron-donating moiety methoxyphenyl and electron-accepting moiety bromophenyl as a terminal group respectively. Two monomers MAzo-OCH 3 and MAzo-Br based on them were also synthesized and corresponding homopolymers PAzo-OCH 3 and PAzo-Br were prepared by free radical polymerization. Azo-OCH ...
Two water soluble conjugated polymers, poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) and ammonium ion stabilized poly(phenylene vinylene) (P2), are found to be able to reduce noble metal ions to zero-valent metals via a direct chemical deposition technique. Au nanoparticle clusters can be obtained through reduction of Au 3+ ions by PEDOT:PSS and the electronic coupling...
Phenylboronic acid-containing thermo-responsive block copolymer, poly(ethylene oxide)-b-poly(methoxydi(ethylene glycol) methacrylate-co- aminophenylboronic acid ethyl methacrylate) (PEO-b-P(DEGMMA-co-PBAMA)), was employed to investigate the multiple micellization and dissociation transitions. The unique sugar- and pH-responsive properties of phenylboronic acid were interesting to provide two parallel...
We report here the preparation of nanostructured polypyrroles (PPys) with different morphologies (nanospherical or nanofibrillar) through a surfactant-assisted oxidative polymerization route. Nanofibrillar PPy has a higher redox current, presumably due to a higher surface area accessible to the electrolytes and a lower charge transfer resistance compared to that of the spherical PPy. The impedance...
Bidirectional alkoxyamine 2 was synthesized and used as the initiator in the polymerization of styrene (S), n-butyl acrylate (nBA), t-butyl acrylate (tBA), isoprene (I), and dimethylacrylamide (DMA). A variety of symmetrical ABA triblock copolymers were prepared, ranging in size from 5 to 59kDa. Kinetics studies and gel permeation chromatography (GPC) confirmed the “living” nature of these polymerizations...
