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

摘要

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