N2 - 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.
