We report a new strategy, viz. cascade photocaging, for protecting diethylamine diazeniumdiolate (O-position), a light sensitive molecule. Upon photolysis, the cascade photocage at first releases the light activatable linker (latent fluorophore) O-caged diazeniumdiolate, which undergoes spontaneous 1,8-elimination, triggering the release of the diazeniumdiolate anion and the fluorophore.
我们报道了一种用于保护光敏感分子二乙胺二氮烯二醇盐（O-位）的新策略，即级联光笼化。光解时，级联光笼首先释放出可光激活的连接子（潜在荧光团）O-笼化二氮烯二醇盐，其发生自发的1,8-消除反应，引发二氮烯二醇盐阴离子和荧光团的释放。
