A multiply photoactive compound has been developed based on quaternized 1,2-bis(4'-pyridyl)ethylene, which exhibits a hierarchical photoreaction by controlling light intensity. Weak ultraviolet light can effectively promote the cycloaddition reaction with fluorescence enhancement, while stronger ultraviolet light can stimulate a complex response of cycloaddition and electron-transfer which shows turn-off luminescence and coloration. Photofacilitated bleaching of the colored products has been observed for the first time in the pyridinium family.
一种多光活性化合物已被开发出来，该化合物基于季铵化的 1,2-双(4'-吡啶基)乙烯，通过控制光强可实现分级光反应。弱紫外光可以有效地促进环加成反应，并伴有荧光增强，而较强的紫外光可以刺激环加成和电子转移的复杂反应，表现为荧光猝灭和显色。在吡啶鎓家族中首次观察到光致褪色的有色产物。
