A new triazole‐functionalized tetracarboxylic acid ligand (H 4 L) has been synthesized and utilized for the fabrication of a 3D Zn II organic framework with a Zn 4 (−COO) 6 cluster as the secondary building unit. The framework exhibits very good thermal stability and consists of dual functionalities of exposed Lewis acidic metal sites and accessible nitrogen‐donor Lewis basic sites. The Lewis basic nitrogen sites in the framework serve as CO 2 binding sites for highly selective CO 2 capture and the presence of exposed Lewis acidic metal sites in the framework make it an efficient heterogeneous catalyst for the chemical fixation of CO 2 into value‐added cyclic carbonates under ambient conditions.
