Preparation and characterization of chromophor group containing cyclotriphosphazenes: I imino chromophor carrying some cyclotriphosphazenes

Article abstract of DOI:10.1080/10426509908031613

Some new substituted cyclotriphosphazenes were prepared by the reaction of hexachlorocyclotriphophazene and 4-hydroxy or 4′-hydroxy Schiff bases as 4′-hydroxybenzylideneaniline, 4′-hydroxy-4-chlorobenzylideneaniline, 4′-hydroxy-2-chlorobenzylidenaniline, 4′-hydroxyfurfurylidenaniline, 4-hydroxybenzylidene-2′-methylaniline, 4-hydroxybenzylidene-2′,6′-dimethylaniline, 4-hydroxybenzylidene-2′-chloroaniline, 4-hydroxybenzylidene-4′-tert-butylaniline, 4′-hydroxybenzylidene-3,4-15-Crown-5-aniline. The structure of compounds with a general formula [NP(OC₆H₄CH=N-Ar)₂]₃, or [NP(OC₆H₄N=CH-Ar)₂]₃, was determined by IR, UV, ¹H-NMR and elemental analysis. IR spectra of all compounds showed four characteristic bands located at 1633-1601cm^-1, 1242-1150cm^-1, 1278-1261cm^-1 and 958-943cm^-1, respectively, corresponding to CH=N, P=N, P-N-P (asymmetric) and P-N-P (symmetric) vibrations. Charasterictic UV bands, named as Band I, Band II, Band III and Band IV located at 346-308nm, 294-271nm, 262-216nm and 240-210nm respectively, are due to electronic transitions. The ¹H-NMR spectra of 4-hydroxyfurfurylidene and the phosphazene derivative shows cis-trans izomerization below 305°K and 295°K.
