[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 oligothiophenes exhibit intriguing reversible oxidation and reduction redox behavior.
[反应：见正文] 通过铃木偶联反应以良好的产率合成了一系列新型的9,9-二芳基芴封端的低聚噻吩。发射颜色可通过改变低聚噻吩核的共轭长度来控制。所得低聚物庞大且刚性的端基对其高形态和热稳定性非常有利。这些新型低聚噻吩表现出有趣的可逆氧化和还原氧化还原行为。
