Synthesis of Styrylpyrimidine and Its Spectral Characteristic as a pH Probe
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.
