Abstract

π-Conjugated, narrow band gap copolymers containing pyridal[2,1,3] thiadiazole (PT) were synthesized via starting materials that prevent random incorporation of the PT heterocycles relative to the backbone vector. Two regioregular structures could be obtained: in one the PTs are oriented in the same direction, and in the other the orientation of the PTs alternates every other repeat unit. Compared to their regiorandom counterparts, the regioregular polymers exhibit a 2 orders of magnitude increase of the hole mobilites, from 0.005 to 0.6 cm2 V-1 s-1, as determined by field-effect transistor measurements. © 2011 American Chemical Society.
