摘　　要：实验设计合成了对Fe3+/Cu2+具有良好选择性的荧光化学敏感器2,3,4,5-四苯基联苯胺(D).化合物D的乙醇溶液在加入FeCl3或CuCl2后,荧光发生了猝灭.进一步的实验表明,硝酸铁的加入也会使化合物D的荧光猝灭而硫酸铁几乎没有什么影响;对于铜盐,醋酸铜的加入使化合物D的荧光猝灭,而硝酸铜和硫酸铜不能使其完全猝灭.A fluorescent chemodosimeter p-(2,3,4,5-tetraephenyl)-phenylaniline(D) which shows excellent selectivity tow ards Fe 3 + / Cu 2 + is synthesized.Upon addition of FeCl 3 or CuCl 2 into the ethanol solution of D,it exhibits a great decrease of emission intensity against environmental and biological samples.Further experiments demonstrate that Fe(NO 3) 3 has the similar influence as FeCl 3 w hile Fe 2(SO 4) 3 has no influence on the emission spectra of D;as for copper salts,copper acetate has the similar influence as CuCl 2 w hile copper nitrate and copper sulfate cannot make the emission intensity of D quench completely.
