产品介绍

碘化反式-4- [4-(二甲基氨基)苯乙烯基] -1-甲基吡啶鎓(DASPI)是一种半菁染料。反式-4-[4-(二甲基氨基)苯乙烯]-1-甲基吡啶碘(DASP)是一种可作为荧光探针的半氰基染料。可通过调节溶液的pH值而对其荧光属性进行调节。它能被光激发以形成能够实现分子间电荷转移态的内捻。


应用

DASP可用来对分子筛晶体的荧光进行表征,从而进一步用于光功能材料的开发。

trans-4-[4-(Dimethylamino)styryl]-1-methylpyridinium iodide (DASP) is a hemicyanine dye that can be used as a fluorescence probe. Its fluorescent property can be tuned by adjusting the pH of the solution. It can be photoexcited for internal twisting that forms intermolecular charge transfer state.
trans-4-[4-(dimethylamino)-styryl]-1-methylpyridinium iodide (DASPI) is a hemicyanine dye.
Application:

DASP can be used to characterize the fluorescence of zeolite crystals which can further be used in the development of photofunctional materials.
