Abstract: Without employing protection or deprotection steps, a novel series of fluorescent triazine dendri-mers of three generations containing of a single, focally located 1,4,5,8-naphthalimide-based core and 8, 16 ethyl peripheral groups were synthesized with convergent approaches, and fully characterized via IR, 1H NMR, 13C NMR and elemental analyses. Using this method, a mild reaction condition was allowed, and an excellent yield was obtained. Their fluorescent properties in dichlomethane were studied. The results indicate that the triazine dendrimers have stronger fluorescence, and their intensity increased according to generation number increase.

Key words: Dendrimer, 1,4,5,8-Naphthalimide, Fluorescence intensity
