Since the molecular structures based on donor-pi-acceptor dye shows good optical absorption and emission properties by push-pull chromophore system, donor-pi-acceptor dyes have been intensively studied as functional key materials. In this study, the new donor-pi acceptor dyes were designed, synthesized and characterized. The absorption and fluorescence emission spectra of these dyes, being related with chromic color changes, were determined with the several solvents of widely different polarities. The electron energy states of dyes were also characterized by theoretical calculations.
