摘 要:Two novel cyclotriphosphazene derivatives containing 6- (4-hydroxyphenyl)-2,2′-bipyridine (hopbp) side groups, N3 P3 (dobp) 2 (hopbp) 2 ( 1 ) and N3 P3 (dobp) (hopbp) 4 (2) ( dobp = 2,2′-dioxybiphenyl), were synthesized and characterized. These compounds display strong fluorescent emission both in solution and in solid state. Their absorption and emission spectra are sensitive to proton: the addition of HBF4 to the methanol and dichloromethane solution(9: 1, volume ratio) of compound 1 led to a red-shift from 350 to 460 nm for the emission spectrum, and the process was also characterized by isosbestic points of absorption spectra at 267, 287 and 313 nm.
