摘　　要：比较研究了铜、镍的杯 [4 ]芳烃光学受体及其单体的分析性能 ,并进一步探讨了杯 [4 ]芳烃的锥形骨架在分子识别中的作用。结果表明 ,通过分子设计 ,将杯 [4 ]芳烃锥形骨架合理地引至光学受体中 ,可以起到立体屏障作用 ,能有效阻止其它客体在一些方向上靠近配位反应点所带来的干扰 ,从而对客体的选择性识别提供重要贡献。In order to understand further the role of calix[4] arene skeleton with cone conformation in recognition of spectroscopic acceptors, a comparative study was made on calix[4]arenes and their monomers, including the design and properties of calix[4]arene-based chromoionophore foe Ni2+ and especially fluorescent acceptor for Cu2+. The results show that calix[4] arene skeleton with cone conformation, introduced rationally into a designed acceptor, may serve as a shielding or covering unit, which prohibits other guests from approaching reaction sites at least in one direction and can thus make a contribution to the selectivity.
