In this research, the photophysical properties of 4-(2-aminoethylene) amino- N- allyl- 1,8-naphthalimide and its methylmethacrylate copolymer were investigated. Fluorescence spectrum of its thin film copolymer taken at different pH solutions suggest that it could be used as fluorescent pH sensors. The results showed that fluorescence emission of the polymer film dramatically decreased while pH is increased. Also, solvatochromism behavior of dye in various solvents has been evaluated. The fluorescence properties of this dye are so strongly affected by the nature of the solvent polarity in which the emission of molecule can be considered to be switched off when a solvent polarity is increased.
