通过Cu（NO3）（2）中心点3 H（2）O与2，4，6-三（4-吡啶基）吡啶（pytpy）在混合溶剂中的自组装反应，合成了一种新的Cu（I）金属有机骨架，{[Cu（pytpy）] centerdotNO 3 centerdotCH 3OH}（infinity）（1），它是一种具有（10，3）-B拓扑结构的4重互穿三维骨架. 1通道中的客体甲醇分子可以通过单晶到单晶（SC-SC）过程被水分子取代，并且水合复合物可以作为具有不同几何形状的阴离子的主体，可以方便地视觉识别。此外，去溶剂化的复合物在环境温度下显示出对CO2的选择性吸收超过N-2。
A new Cu(I) metal-organic framework, {[Cu(pytpy)]center dot NO3 center dot CH3OH}(infinity) (1), which is a 4-fold interpenetrating 3D framework with (10,3)-b topology, has been synthesized by self-assembly of Cu(NO3)(2)center dot 3H(2)O with 2,4,6-tris(4-pyridyl)pyridine (pytpy) in mixed-solvent. The guest methanol molecules in the channels of 1 could be replaced by water molecules via a single-crystal-to-single-crystal (SC-SC) process, and the hydrated complex could serve as a host for sensing anions with different geometries which can be conveniently recognized visually. Moreover, the desolvated complex shows selective uptake of CO2 over N-2 at ambient temperature.
