Abstract

A two-dimensional Kagomé-type MOF (Azln-KGM) incorporating 1,3-azulenedicarboxylate ligands was synthesized. Compared with reported isomorphous MOFs featuring a benzene motif, Azln-KGM exhibited an enhanced maximum adsorption capacity and gate-opening behavior accompanied by larger structural changes.
