Abstract
AbstractHexa(2‐formylphenoxy)cyclotriphosphazene (o‐CHO‐C6H4O)6N3P3 (2) was obtained from the reaction of hexachlorocyclotriphosphazene (1) with salicylaldehyde in the presence of K2CO3 in THF solvent. A series of Schiff bases containing cyclotriphosphazenes such as [o‐(C6H5N=CH)C6H4O]6N3P3 (3), [o‐(1‐C10H7N=CH)C6H4O]6N3P3 (4), [o‐(p‐HOC6H4N=CH)C6H4O]6N3P3 (5), [o‐(2,3‐Cl2C6H3N=CH)C6H4O]6N3P3 (6), [o‐(3,4‐Cl2C6H3N=CH)C6H4O]6N3P3 (7), [o‐(3,5‐(CH3)2C6H3N=CH)C6H4O]6N3P3 (8), [o‐(C6H5CH2N=CH)C6H4O]6N3P3 (9), [o‐(p‐CH3OC6H4CH2N=CH)C6H4O]6N3P3 (10), [o‐(n‐CH3CH2CH2CH2N=CH)C6H4O]6N3P3 (11), [o‐(t‐(CH3)3CN=CH)C6H4O]6N3P3 (12), [o‐(n‐CH3[CH2]10CH2N=CH)C6H4O]6N3P3 (13) were synthesized from the reaction of hexa(2‐formylphenoxy)cyclotriphosphazene (2) with aniline, 1‐naphthylamine, 2‐aminophenol, 2,3‐dichloroaniline, 3,4‐dichloroaniline, 3,5‐di‐tert‐butylaniline, benzylamine, p‐methoxybenzylamine, n‐butylamine, tert‐butylamine and 1‐dodecylamine, respectively. The synthesized compounds were obtained in good yield and high purity. The structures of the compounds were confirmed by means of IR, NMR(1H, 13C, 31P) and elemental analysis. Photophysical properties of the cyclotriphosphazene derivates were investigated in dichloromethane solvent by UV‐Vis. spectrophotometry and spectrofluorometry (emission and excitation). Among the synthesized cyclotriphosphazene derivates, the compounds 2, 4, 5, 11 and 12 exhibit emission between 390 and 550 nm at room temperature.
