Preparation and Characterization of Chromophor Group Containing Cyclotriphosphazenes: II Azo Chromophor Carrying Some Cyclotriphosphazenes

Abstract

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(OC<inf>6</inf>H<inf>4</inf>N=N-Ar)<inf>2</inf>]<inf>3</inf>. was determined by UV-VIS, IR, 1H-NMR and elemental analysis.
