ABSTRACT
Metal–organic frameworks (MOFs) featuring accessible Cu(I) sites exhibit exceptional properties, garnering significant attention for applications such as the selective adsorption of π-acidic gases. Benzotriazolate ligands represent an ideal platform for constructing such MOFs; however, most reported systems are based on linear, ditopic linkers, limiting the spatial arrangement of Cu(I) sites within the framework and consequently their functionalities. Herein, we report the assembly of tetratopic benzotriazolate ligands with Cu(I) ions into a single-crystalline MOF—Cu-TBT—displaying a rod-packing structure with hqz net and incorporating linearly coordinatively unsaturated Cu(I) sites. Cu-TBT possesses an open pore architecture with Cu(I) sites, showing a significantly enhanced affinity for CO over N2 and H2, as supported by adsorption, spectroscopic and simulation studies. This work suggests that increasing the ligand connectivity is an effective strategy for regulating the spatial distribution of accessible low-valent metal sites, paving the way for unlocking crystalline porous materials for π-acidic gas adsorption.
