Preparation and Characterization of Chromophore Group Containing Cyclotriphosphazenes: V. Spectroscopic Investigation of Some Hexakis(p-Phenylazo

Abstract

Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlorocyclotriphosphazene and 4-phenylazo-1-naphthol compounds such as 4-phenylazo-1-naphthol, 4-(2-chlorophenylazo)-1-naphthol, 4-(3-chlorophenylazo)-1-naphthol, 4-(4-chlorophenylazo)-1-naphthol, 4-(4-florophenylazo)-1-naphthol, 4-(4-bromophenylazo)-1-naphthol, 4-(4-iyodophenylazo)-1-naphthol, 4-(4-acetylphenylazo)-1-naphthol, 4-(4-methylphenylazo)-1-naphthol, 4-(4-ethylphenylazo)-1-naphthol, 4-(3,4-dimethylphenylazo)-1-naphthol, 4-(2,4-dichlorophenylazo)-1-naphthol, 4-(2,6-dichlorophenylazo)-1-naphthol and 4-(2,6-dimethylphenylazo)-1-naphthol. The structure of these compounds with a general formula [NP(OC<inf>10</inf>H<inf>6</inf>N = NAr)<inf>2</inf>]<inf>3</inf>, was determined by UV-vis, FT-IR, 1H NMR and elemental analysis. © 2005 Elsevier Ltd.
