    醌核不对称取代的最小低聚噻吩双自由基
    摘要:
    不对称共轭双自由基具有迷人的电子特性,但由于其合成的挑战和自由基单元的精细选择过程而很少被发现。在此,我们报告了一系列不对称双自由基 PTI -n(n = 0 至 4),其中不同数量的醌式噻吩单元作为 π 桥,苯氧基和咪唑基部分作为自由基中心。由于从二噻吩传递到三噻吩衍生物时从闭壳到开壳单线态基态的转变,这种结合提供了表现出超过 1200 nm 的优异红外吸收特性的二元组。四噻吩分子具有消失的单重态-三重态能隙和显着的蓝移(ca.400 nm)在电子吸收光谱中。这些只有四个单元的醌式低聚噻吩的电子和光学性质的调制是前所未有的,并突出了这些核心的不对称取代作为开发共轭分子领域的肥沃利基。
