[reaction: see text] A series of novel 9,9-diarylfluorene-capped oligothiophenes were synthesized by Suzuki coupling reactions in good yields. The color of the emissions can be controlled by varying the conjugation length of the oligothiophene core. The bulky and rigid terminal groups of the resulting oligomers are significantly beneficial for their high morphological and thermal stability. These new
[反应:见正文]通过Suzuki偶联反应以高收率合成了一系列新型的9,9-二芳基芴封端的低聚噻吩。发射的颜色可以通过改变寡聚噻吩核的缀合长度来控制。所得的低聚物的庞大和刚性的末端基团由于其高的形态学和热稳定性而显着有益。这些新的低聚噻吩表现出有趣的可逆氧化和还原氧化还原行为。
