Extended Calix[4]arene Analogues by Two P−Cu^I−P Bridges and Anion Encapsulation

Two novel extended calix[4]arene analogues by two P−CuI−P bridges have been synthesized. The molecular structures and anion encapsulation ability for ClO4- and BF4- have been studied by X-ray analysis.通过两条P−CuI−P桥联结构，合成了两种新型扩展杯[4]芳烃（calix[4]arene）类似物。采用X射线分析，对其分子结构以及对高氯酸根（ClO₄⁻）、四氟硼酸根（BF₄⁻）的阴离子包合性能进行了研究。
