Abstract

A series of robust and inexpensive p-type organic semiconductors 1,3,8,10-tetramethyl quinacridone compounds was prepared. These quinacridone compounds bearing N,N′-disubstituted long N-alkyl chains self-organize into highly oriented crystalline films, leading to high performance organic thin film transistors with the best field-effect mobility, on/off ratio, and threshold voltage being 1.6×10−1 cm2 V−1 s−1, 1×104, and −17 V, respectively. The effects of methyl substituent and N-alkyl chain length of the quinacridone compounds together with the molecular packing on the field-effect mobility are discussed.
