Zeolite NPO‐Type Azolate Frameworks
Abstract Three‐membered rings (3‐rings) are an important structural motif in zeolite chemistry, but their formation remains serendipitous in reticular chemistry when designing zeolitic imidazolate frameworks (ZIFs). Herein, we report a design principle for constructing four new ZIFs, termed ZIF‐1001 to ‐1004, from tetrahedral Zn II centers (T), benzotriazolate (bTZ), and different functionalized benzimidazolates (RbIM) that adopt a new zeolite NPO‐type topology built from 3‐rings. Two factors were critical for this discovery: i) incorporating the bTZ linker within the structures formed 3‐rings due to a ∠(T−bTZ−T) angle of 120–130° reminiscent of the ∠(Ge−O−Ge) angle (130°) observed in germanate zeolite‐type structures having 3‐rings; and ii) RbIM guided the coordination chemistry of bTZ to bind preferentially in an imidazolate‐type mode. This series’ ability to selectively capture CO2 from high‐humidity flue gas and trap ethane from tail gas during shale gas extraction was demonstrated..
