| Abstract: | A fluorescent monomer was synthesized from 4-bromo 1,8-naphthalic anhydride and diethylenetriamine,and cyanuric chloride via amidation,nucleophilic substitution.Then a water-soluble fluorescent polymer was obtained by copolymerization between it with acrylamide.The structure was characterized by Fourier transform infrared spectra(FT-IR),ultraviolet-visible absorption and fluorescence spectra of the target product were investigated.The research result shows that the stokes shift of polymer(3964 cm-1) is less than monomer(6512 cm-1), the active fluorescent chromophores of the polymeric fluorescent material which was bonded in the macromolecule chains can enhance chromogen photochemical stability.The reason is that the molecules from the ground state transition to the excited state,the fluorescent polymer steric resistance change is small and less energy loss.The photophysics and photochemical properties of fluorescent polymer are markedly determined by solvent polarity. |
