Abstract

The indigoid-type dyes based on isatin α-chloride were synthesized and the dyes were discussed with relevance to the H-chromophore or cross-conjugated chromophore.The color-changed properties of the dyes were also investigated by means of visible absorption spectra. The novel dyes from isatin α-chloride are of theoretical interest and such dyes can be used as continuous pH indicators in acid/base titrimetric analyses.
