Simple synthesis of end functionalized regioregular poly(3‐hexyl thiophene) by catalytic‐initiated Kumada catalyst transfer polymerization

Abstract

A simple but efficient route to the preparation of aromatic end‐functionalized regioregular poly(3‐hexyl thiophene) through catalytic initiated Kumada catalyst transfer polymerization from easily accessible reagents is reported here. The introduction of an aromatic moiety at one end of the poly(3‐hexyl‐thiophene) (P3HT) chain was confirmed by NMR, by MALDI‐TOF analysis, and also by successful syntheis of rod–coil‐conjugated block copolymers either from a proper end‐functionalized P3HT or from an end‐functionalized coil polymer.
