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(diethyl-hexyl-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.
