A new polymer blend formed by poly(3-hexylthiophene)-poly(4-vinylpyridine) (P3HT- P4VP) block copolymers and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) is reported. The P4VP and PCBM are mixed together by weak supramolecular interactions, and the resulting materials exhibit microphase separated morphologies of electron-donor and electron-acceptor rich domains. The properties of the blend,...

Atom transfer radical polymerization (ATRP) was used as a versatile route to well-defined poly(diethylhexyl-p-phenylenevinylene-b-styrene) (PPV-b-PS) semiconducting block copolymers. For this purpose, original conjugated macroinitiators were synthesized from DEH-PPV and further used for the copolymerization reaction. The microphase-separated morphologies obtained with the semiconducting PPV-b-PS...
