Unique structural micro-adjustments in a new benzothiadiazole-derived Zn(II) metal organic framework via simple photochemical decarboxylation

The first example of micro-adjustments of a metal organic framework (MOF) structure was observed in a new Zn(II) MOF (Zn-BTDC-M1) derived from a benzothiadiazole-4,7-dicarboxylic acid (H2BTDC) ligand using a light-driven decarboxylation process. Interestingly, such decarboxylation occurs at the non-chelated wing of the ligand, which induced a change in the capability of the MOF for physical N2 adsorption and chemical NH3 gas adsorption.
