Synthesis and characterization of fluorescence light emitting rhodamine derivative schiff base compounds

In this study, starting reagents 2- (2-aminoetil)-3´,6´-bis (dietilamino) spiro [izoindol-1,9´- ksanten]-3-on (1) and 2-(2-aminoetil)-3´,6´-bis (etilamino)-2´,7´-dimetil [izoindol-1,9-ksanten ]-3-on(2) were obtained from the reaction of dyes Rhodamine Band Rhodamine 6G containing xanthene ring with ethylenediamine. 14 new compounds were synthesized from the reactions of the starting materials (1) and (2) and the starting materials of the benzenesulfonate derivative (BS). The molecular structures of the compounds obtained were characterized by FT-IR, NMR and HR-MS.
