Photoluminescence properties of three d10 complexes constructed from the bifunctional benzimidazole-carboxylate-based connector

The structural diversities elucidate that the nature of ligand and anions have pronounced influences on the formations of complexes 1-3. The emission discrepancy of three complexes indicates the structure-property relationship of MOF material. Compared to 3, the strong phosphorescence behaviors for 1 and 2 due to the Ag(I) heavy atom effect.
