Preparation and characterization of chromophore group containing cyclotriphosphazenes: IV spectroscopic and thermal investigation of some hexakis( p-phenylazo-o-allylphenoxy)cyclotriphosphazenes

Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlorocyclotriphosphazene and 3-allyl-4-hydroxyazo compounds such as 3-allyl-4-hydroxyazobenzene, 40-chloro-3-allyl-4-hydroxyazobenzene, 40-methyl-3-allyl-4-hydroxyazobenzene, 40- bromo-3-allyl-4-hydroxyazobenzene, 40-acetyl-3-allyl-4-hydroxyazobenzene, 30,40-dimethyl-3-allyl-4-hydroxyazobenzene and 40-iodo-3- allyl-4-hydroxyazobenzene. They are characterized by UV–VIS, FT-IR, 1H-NMR, 13C-NMR, elemental analysis, TG, DTG and DTA. q 2004 Elsevier B.V. All rights reserved.
