Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlorocyclotriphosphazene and 4-hydroxyazo compounds such as 4-hydroxyazobenzene, 4′-ethyl-4-hydroxyazobenzene, 4′-tertbutyl-4-hydroxyazobenzene, 4′-methoxy-4-hydroxyazobenzene, 3′,4′-dichloro-4-hydroxyazobenzene, 2′-chloro-4-hydroxyazobenzene and 2′-methoxy-5′-chloro -4-hydroxyazobenzene. The structure of the compounds with the general formula [NP(OC6H4N=N-Ar)2]3. was determined by UV-VIS, IR, 1H-NMR and elemental analysis.
