Preparation and characterization of chromophore group containing cyclotriphosphazenes: V. Spectroscopic investigation of some hexakis(p-phenylazo-alpha-naphtoxy)cyclotriphosphazenes

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,1 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(OC10H6N = NAr)(2)](3), was determined by UV-vis, FT-IR, H-1 NMR and elemental analysis. (c) 2005 Elsevier Ltd. All rights reserved.
