Abstract

original image

A narrow bandgap polymeric semiconductor, BOC-PTDPP, composed of an alkyl substituted diketopyrrolopyrrole (DPP) and tert-butoxycarbonyl (t-BOC)-protected DPP, is synthesized with a view toward forming hydrogen-bonded networks after the thermal cleavage of t-BOC groups. On page 4128 Joon Hak Oh, Changduk Yang, and co-workers report that the dominant polarity in ambipolar organic transistors based on BOC-PTDPP changes from positive to negative after the thermal cleavage of t-BOC groups.
