A novel class of pyronin analogues, which undergoes a photochemically induced cleavage of the C-C bond in the presence of water in both solution and on a silica gel surface upon direct irradiation with visible light, is reported. The reaction course can be monitored by characteristic fluorescence of both the starting compound and the final product. This system could find useful applications in the field of photoremovable protecting groups or caged fluorophores.
报道了一类新型的派洛宁类似物,在可见光直接照射下,该类似物在水的存在下,无论是在溶液中还是在硅胶表面,都会发生 C-C 键的光诱导断裂。反应过程可以通过起始化合物和最终产物的特征荧光进行监测。该体系在光脱保护基团或笼状荧光团领域可能有潜在的应用。
