Preparation and characterization of chromophor group containing cyclotriphosphazenes: II azo chromophor carrying some cyclotriphosphazenes
Özet
Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlrocyclotriphosphazene and 4-hydroxyazo compounds such as 4-hydroxyazobenzene, 4'-ethyl-4-hydroxyazobenzene, 4'-tertbutyl-4-hydroxyazobenzene, 4'-methoxy-1-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, II-NMR and elemental analysis.
