在不含[AuCl 4](-)的HNO 3水溶液和含[AuCl 4](-)的HCl和HNO 3水溶液中均可以得到Q[8]基蜂窝状骨架。Q[8]与平面无机阴离子[AuCl 4](-)和NO3-的外表面相互作用是主要的驱动力。这些骨架对[AuCl 4](-)的吸附具有很高的选择性,可以建立一个回收金的方法。
Q[8]-based honeycomb-like frameworks can be obtained in [AuCl4](-)-free aqueous HNO3 solution and aqueous HCl and HNO3 solutions that contain [AuCl4](-). The outer surface interaction of Q[8] with planar inorganic anions [AuCl4](-) and NO3- is the main driving force. These frameworks exhibit a high selectivity for imprisoning [AuCl4](-) that could establish a process for gold recovery.
