A facile synthesis of air-stable anthra[1,2-b:4,3-b':5,6-b'':8,7-b''']tetrathiophene derivatives 1a and 1b has been developed for applications in organic thin film transistors. Both molecules tend to self-associate through pi-pi stacking in solution and in different films. The hole mobility of 0.012 cm2 V(-1) s(-1) is obtained from 1a due to morphology changes in films from less ordered to highly ordered structures after thermal annealing. Good performance remained persistent over a period of 14 days, indicating the high stability of such transistors.
已开发出一种简便的方法来合成空气稳定的蒽[1,2-b:4,3-b':5,6-b'':8,7-b''']四噻吩衍生物1a和1b，用于有机薄膜晶体管。这两种分子在溶液和不同薄膜中都倾向于通过π-π堆积进行自缔合。由于热退火后薄膜形态从无序结构变为高度有序结构，1a的空穴迁移率为0.012 cm2 V(-1) s(-1)。在14天的时间里，器件性能一直保持良好，表明此类晶体管具有很高的稳定性。
