Control of Morphology of Polythiophene-based Block Copolymers for Organic Electronic Application

초록

A series of well defined block copolymers of 3-hexylthiophene and methacrylate derivates were synthesized by combination of ATRP and GRIM. Obtained block copolymers with narrow polydispersity (PDI < 1.2) had various molecular weights with different weight fraction of P3HT. The block copolymers were then examined morphology changes by various solvents, which were selectively or both soluble for each block segments. Selective alignments of P3HT domains with a preferred conducting path applied for organic electronic applications such as organic thin film transistor and photovoltaic cell.
