We report the synthesis, characterization, microphase separation, field-effect charge transport, and photovoltaic properties of regioregular poly(3-hexylthiophene)-b-poly(3-cyclohexylthiophene) (P3HT-b-P3cHT). Two compositions of P3HT-b-P3cHT (HcH63 and HcH77) were synthesized with weight-average molecular weights of 155,500 and 210,800 and polydispersity indices of 1.45 and...

We investigate the complexation of ampholytic poly(N-isopropylacylamide)-block-poly- (L-glutamic acid)-block-poly(L-lysine) (PNiPAM-b-PLG-b-PLLys) triblock copolymers and PNiPAM-block-(PLG-co-PLLys) diblock copolymers with counter charged anionic and cationic surfactants. Both triblock and diblock copolymers are able to selectively form complexes...

We have synthesized a series of poly[4-(9,9-dihexylfluoren-2-yl)styrene]-block-poly(2-vinylpyridine) (P(St-F1)-b-P2VP) and poly[4-di(9,9-dihexylfluoren-2-yl)styrene]-block-poly(2-vinylpyridine) (P(St-F1₂)-b-P2VP) comblike block copolymers and investigated their self-assembly behavior. The block composition, molecular weight, and the length of the fluorene side chain...

Complexation of dendronized block copolymers with sulfate alkyl tails forms unprecedented hierarchically ordered bulk structures, including rectangular-in-lamellar, tetragonal-in-lamellar, hexagonal-in-lamellar and lamellar-in-lamellar. These novel liquid-crystalline morphologies, which can be designed at low length scales in these systems, are expected to provide final materials with not only...

We report on the dependence of proton conductivity on the morphologies of sulfonated polystyrene−poly(methyl methacrylate) (sPS−PMMA) diblock copolymers. Three different diblock copolymers of varying molecular weight and block volume fraction were studied, and for each one several sulfonation degrees of the PS block were considered. The investigation of the morphologies of the...
