Abstract	Researchers constructed a highly porous metal–organic framework (MOF) incorporating both exposed metal sites and nitrogen-rich triazole groups via solvothermal assembly of a clicked octcarboxylate ligand and Cu(II) ions, presenting a high affinity toward CO2 molecules clearly verified by gas adsorption and Raman spectral detection. The constructed MOF featuring CO2-adsorbing property and exposed Lewis-acid metal sites is potentially an excellent catalyst for CO2-based chemical fixation. The synthesized MOF exhibits high catalytic selectivity to different substrates on account of the confinement of the pore diameter. The high efficiency and size-dependent selectivity toward small epoxides on catalytic CO2 cycloaddition make this MOF a promising heterogeneous catalyst for carbon fixation.
