the synthesis, photophysical and electrochemical properties and their interplay, and our theoretical calculations. These molecules are composed of two fluorophores, an electron-rich triphenylamine unit and an electron-poor tetrazine unit. Although the bichromophores are not fluorescent in the neutral state due to a photoinduced electron transfer from the triphenylamine unit to the tetrazine unit, one
已经制备了原始的新型荧光和电活性化合物,它们具有通过氧原子间隔键连接的两个不同的荧光基团。我们在这里描述了合成、光物理和电化学性质及其相互作用,以及我们的理论计算。这些分子由两个荧光团、一个富电子三苯胺单元和一个缺电子四嗪单元组成。尽管由于从三苯胺单元到四嗪单元的光诱导电子转移,双色团在中性状态下不发荧光,但可以通过三苯胺部分的氧化来恢复荧光。因此,已经实现了氧化还原荧光开关。
