Patternable solution-crystallized organic transistors with high charge carrier mobility

Abstract

Patternable solution-crystallized organic transistors are developed with very high carrier mobility that exceeds 10 cm2 V-1 s -1. The devices feature a newly synthesized air-stable compound 2,9-didecyldi-naphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene (C10-DNTT) and are formed from hot solution. A method of oriented growth is introduced to obtain the single-crystalline films of C10-DNTT, regulating the crystallizing direction and the positions in a single process. © 2011 WILEY-VCH Verlag GmbH & Co.
