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

ChEBI: 4-[4-(dimethylamino)styryl]-N-methylpyridinium iodide is an organic iodide salt consisting of pyridinium iodide having a methyl substituent at the 1-position and a 4-dimethylaminostyryl substituent at the 4-position. It has a role as a fluorochrome. It is an organic iodide salt and a pyridinium salt. It contains a 4-[4-(dimethylamino)styryl]-N-methylpyridinium.

trans-4-[4-(dimethylamino)-styryl]-1-methylpyridinium iodide (DASPI) is a hemicyanine dye.
