and its reference systems were investigated through UV/Vis absorption, fluorescence, and time‐resolved fluorescence spectroscopy. An efficient energy‐transfer process in [3]rotaxane occurred from the OPV donor to the BODIPY acceptor because of the large overlap between the absorption spectrum of the BODIPY moiety and the emission spectrum of the OPV fluorophore; this shows the important potential of
设计并研究了一个双支的[3]轮烷,两个[2]轮烷的臂由一个低聚对苯撑亚
乙烯基(OPV)荧光团隔开。采用difluoroboradiaza-每个[2]轮烷臂小号-indacene(BODIPY)
染料官能化的二苯并[24]冠8大环互锁到在杆部的二苄。证实了[3]轮烷的
化学结构,并由1 H和13表征C NMR光谱和高分辨率ESI质谱。通过紫外/可见吸收,荧光和时间分辨荧光光谱研究了[3]轮烷及其参考体系的光物理性质。[3]轮烷的有效能量转移过程是从OPV供体到BODIPY受体发生的,这是因为BODIPY部分的吸收光谱与OPV荧光团的发射光谱之间存在很大的重叠。这表明该系统在设计功能分子系统方面的重要潜力。
