抄録

A solution of dichloroethane containing crystal violet hydrazide (CVH) underwent a rapid photolytic coloration upon ultraviolet (UV) irradiation. When 5% ethanol-dichloroethane was used as a solvent, the dye formation was more efficient and the 620 nm band for triarylmethane dye continued to increase in intensity as the 270 nm band for CVH decreased. The solvent dependency of the fluorescence spectra clearly showed that raising the ratio of ethanol to dichloroethane accelerated the photoionization of CVH. However, the actual dye formation was not efficient due to substantial reversion to the leuco derivative, 5.
