Description

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