Abstract

A series of P3HT-b-PHA-b-P3HT tri-block and P3HT-b-PHA di-block copolymers were facilely synthesized in one pot. The influence of the block ratio on the optical, microstructural and electrical properties has been investigated. OFETs based on these block copolymers have been fabricated with an improved mobility of 0.052 cm² V⁻¹ s⁻¹via a blending method.
