N-hexyl- 4-bromo-1,8-naphthalimide was synthesized from 4-bromo-1,8-naphthalene anhydride and n-hexylamine, and then, it can be synthesized new naphthalimide derivatives including thiophene with some thiophene derivatives. The yield of the target product, melting point, and the solubility in all kinds of solvent were investigated. The structure of products were characterized through 1H-NMR, 13C-NMR, and UV-vis. The results show that fluorescence spectrums were shifted, which attributing to the different the attraction of electrons for different replace of thiophene ring and different extent of conjugation. And, the 2k compound reflet red light,which is the longest light in all compunds The result is benefit to design a new fluorescent material based 1, 8-naphthalene imide derivatives.
