Functionalized dithienylthiazolo[5, 4-d]thiazoles for solution-processable organic field-effect transistors
A series of 5′-aryl-substituted 2, 5-bis(3′-hexylthiophen- 2′-yl)thiazolo[5, 4-d]thiazole derivatives was synthesized and these expanded semiconductors were investigated as active materials for solution-processable organic field-effect transistors. Field-effect mobilities of up to 10 -3 cm 2V -1s -1...
