Self-assembly of silver(I) perchlorate with a C₃-symmetric tridentate N-donor ligand produces stable crystals with open channels via catenation of 1D ladder-type coordination polymers. The open-channel crystal shows both unprecedented mixture and temperature effects on the adsorption and separation of o-, m-, and p-xylene isomers in a single-crystal-to-single-crystal (SCSC) mode. o-Xylene is not adsorbed into the channel at 5 °C, but is inserted into the channel at room temperature. In particular, the 1 : 1 mixture of o- and m-xylene was adsorbed into the channel in the 1 : 1 mole ratio via intermolecular weak interactions at 5 °C. In addition, the porous crystals are a practical template for structural determination of small liquid hydrocarbons in the SCSC state.

通过一维阶梯的级联，形成异常的多孔晶体：SCSC模式下前所未有的混合物对二甲苯异构体吸附的影响

具有一C ₃对称三齿N-供体配体的高氯酸银（I）的自组装通过一维阶梯型配位聚合物的串联产生具有明渠的稳定晶体。明渠晶体在单晶至单晶（SCSC）模式下对o-，m-和对二甲苯异构体的吸附和分离均表现出前所未有的混合和温度效应。邻二甲苯在5°C下不会吸附到通道中，而是在室温下插入通道中。特别地，1：1混合物ö -和米二甲苯吸附到在1信道：1的摩尔比通过5°C下的分子间弱相互作用。另外，多孔晶体是用于确定SCSC状态下的小液态烃的结构的实用模板。
