Synthesis of poly(paraphenylene vinylene) - polystyrene-based rod-coil block copolymer by atom transfer radical polymerization: Toward a self-organized lamellar semiconducting material

摘要

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 block copolymer fulfill the basic structural requirements required to build efficient organic photovoltaic devices.
