A solution of dichloroethane containing crystal violet hydrazine (CHV) underwent a rapid photolytic coloration upon ultraviolet (UV) irradiation.When 5percent 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 CHV decreased.The solvent dependency of the flurescence spectra clearly showed that raising the ratio of ethanol to dichloroethane accelerated the photoionization of CHV.However, the actual dye formation was not efficient due to substantial reversion to the leuco derivative, 5.
