摘要

A Zn benzotriazolate metal-organic framework (MOF), [Zn(ZnO₂CCH₃)₄(bibta)₃] (1, bibta^2- = 5,5′-bibenzotriazolate), has been subjected to a mild CH₃CO₂ ^-/HCO₃ ^- ligand exchange procedure followed by thermal activation to generate nucleophilic Zn-OH groups that resemble the active site of α-carbonic anhydrase. The postsynthetically modified MOF, [Zn(ZnOH)₄(bibta)₃] (2∗), exhibits excellent performance for trace CO₂ capture and can be regenerated at mild temperatures. IR spectroscopic data and density functional theory (DFT) calculations reveal that intercluster hydrogen bonding interactions augment a Zn-OH/Zn-O₂COH fixation mechanism.
