| 摘 要： | 合成并表征了化合物4,6-二（4′-二乙基胺基）苯乙烯基]嘧啶-2-醇。 通过研究该化合物在不同pH值的磷酸盐缓冲溶液中紫外-可见吸收光谱和荧光光谱的变化，发现λmax约为500 nm的吸收峰在溶液pH=6.78中吸收强度最大。 荧光发射峰随着pH值的升高逐渐减弱，直至淬灭（pH=5.51）。

| 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. |
