苯乙烯嘧啶化合物的合成及其作为pH探针的光谱特点
Synthesis of Styrylpyrimidine and Its Spectral Characteristic as a pH Probe
摘要
Abstract
4,6-Bis[ (4'-diethylamino) styryl] pyrimidin-2-ol was synthesized and characterized. The UV-Vis and fluorescent properties were studied in phosphate buffer solutions at different pH value. The UV-Vis spectral results indicated that the peak located at ～500 nm reaches maximal intensity at pH =6.78. The fluorescent spectra data suggested that the intensity of emission peak decreased with increasing pH value. The fluorescence was quenched when the pH was 5. 51.关键词
