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

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(OC10H6NNAr)2]3, was determined by UV–vis, FT-IR, 1H NMR and elemental analysis.
