摘 要:合成了一系列分别带有香豆素基和α 萘胺基套索冠醚 ,用紫外光谱法测定了这些套索冠醚与Cu2 + ,Pb2 + ,Cd2 + ,Hg2 + ,Cr3+ ,Ni2 + ,Mg2 + ,Zn2 + 金属离子的络合作用 ,及所形成络合物的λmax及摩尔消光系数ε,发现其中一些化合物对Pb2 + ,Hg2 + ,Cr3+Diazadithiacrown ethers containing two fluorescent side-arms were synthesized, which were used as fluorescent indecator for the following toxic ions in waste water. These crown ethers are 18-crown-6 derivatives with two coumarinyl and naphthalidinyl side-arms, including 3AC, 3Ad, 3Ae, 3Af, 3BC, 3Bd, 3Be, 3Bf, 4Bc, 4Be and 4Bf The shifts, the 1. and the mole absorption coefficent E of these complexes with Cu2+, Pb2+, Cd2+, Hg2+, Cr3+, Ni2+, Mg2+ and Zn2+ ions were measured by UV spectrometry. Some of these ligands can form complexes selectively with Pb2+, Hg2+ and Cr3+.
