Block-copolymers with conjugated segments: Synthesis and structural characterization

We have synthesized and characterized soluble Block copolymers with conjugated sequences (polyparaphenylene: PPP, polythiophene: PT, poly 3 hexylthiophene: PHT) and soluble saturated sequences (polystyrene: PSt, polymethylmethacrylate: PMMA). The studies of some of these copolymers by X ray and neutron scattering show that they are organized in quasi spherical micelles. with a regular porous honeycomb morphology have been prepared with doped and undoped PSt-PPP copolymers by evaporation of their solutions in carbon disulfide.
