【Abstract】 A oligoamide with pyrazoline segment was designed and synthesized.Its structure was identified by IR,MS and 1HNMR.Fluorescence property of the target compoud in solution(DMF) was studied.The results showed that the strongest emission peak was at 442nm and the half peak width was 64nm and the fluorescence quantum yield(Φ) was 73.9%,which enhanced 13% compared to the simple pyrazoline structural unit′s Φ.更多还原
