摘要
Simple structural compounds 1 to 3 were synthesized.The presence of Cu^（2＋） resulted in the fluorescence and absorption spectra change of 1 and 2,which indicated that 1 and 2 showed a highly selective response to Cu^（2＋） over other metal ions.However,3 showed no selectivity for metal ions,which means that the compound could bind with several metal ions,such as,Ni^（2＋）,Zn^（2＋）,Cd^（2＋）.Hg^（2＋）, Pb^（2＋）,Fe^（3＋）,Mg^（2＋）,Ca^（2＋）,and Co^（2＋）,except Cu^（2＋） and Ag~＋.The different spectral responses were attributed to the difference in binding sites for 1 and 3.
