PREPARATION AND CHARACTERAZATION OF CHROMOPHOR GROUP CONTAINING CYCLOTRIPHOSPHAZENES: II AZO CHROMOPHOR CARRYING SOME CYCLOTRIPHOSPHAZENES

Abstract

Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlorocy-clotriphosphazene and 4-hydroxyazo compounds such as 4-hydroxyazobenzene, 4′-ethyl-4-hydroxyazobenzene, 4′-ethyl-4-hydroxyazobenzene, 4′-tertbutyl-4-hydroxyazobenzene, 4′-methoxy-4-hydroxyazobenzene, 3′,4′-dichloro-4-hydroxyazobenzene, 2′-chloro-4-hydroxyazobezene 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.
