Cover Feature: Rational Construction of an Exceptionally Stable MOF Catalyst with Metal‐Adeninate Vertices toward CO₂ Cycloaddition under Mild and Cocatalyst‐Free Conditions (Chem. Eur. J. 49/2019)

Abstract

An exceptionally stable metal–organic framework (MOF) can be rationally constructed by mixed‐ligand strategy, based on ZnII‐adeninate vertices and 2,2′‐dimethyl‐4,4′‐azodibenzoate linkers. The 3D porous MOF not only has a certain amount of CO2 sorption ability but contains rich Lewis acid (ZnII) and basic (−NH2) sites within the confined nanospace. As a result, it can serve as a high‐efficiency heterogeneous catalyst for cycloaddition of CO2 with epoxides to afford cyclic carbonates under mild conditions without solvent or cocatalyst. Moreover, the remarkable stability results in its excellent recyclability for catalytic reactions. More information can be found in the Full Paper by C.‐P. Li, M. Du, et al. on page 11474.
