Synthesis, characterization, and fluorescence phenomena of 1-naphthoxy and 1-naphthylamino substituted cyclotriphosphazenes
Abstract
The reactions of hexachlorocyclotriphosphazene N3P3Cl6 (1) with 1-naphthol and 1-naphthylamine have been examined. The reaction of 1 with sodium 1-naphthoxy gave the hexakis(1-naphthoxy)cyclotriphosphazene (2) in high yield. Geminal 2,2-di(1-naphthylamino)-4,4,6,6-tetrachlorocyclotriphosphazene (3) was obtained from the reaction of 1 with 1-naphthylamine. The structures of phosphazene derivatives were defined by elemental analysis, FTIR, UV--visible, and 1H, 13C, 31P NMR spectroscopy. The fluorescence intensity of the compounds was measured in THF and CH2Cl2. © 2008 Wiley Periodicals, Inc.
