Preparation and Properties of 1,8-Naphthalimide Derivatives Grafted onto Chitosan

Abstract:

A kind of 1,8-naphthalimide derivative grafted onto Chitosan was synthesized with Chitosan, 4-bromo-N-(2-aminoethyl)-1,8-naphthalimide and 4-bromo-1,8- naphthalic anhydride via substitution and amidation. The structures of compounds was characterized by FT-IR．Thermal stability and fluorescence spectra of the target product were investigated. Compared with 4-bromo-N-(2-aminoethyl)-1,8-naphthalimide, the maximum fluorescent intensity of the 1,8-naphthalimide derivative grafted onto Chitosan was increased 1.25 folds.
