A room-temperature phosphorescent metal-organic framework based on proline-tetrazole ligand

In this study, a new compound 1 with the formula as [Cd((S/R)-ptz)2]n was solvothermal synthesized from Cd(II) salt and (S/R)-5-(pyrrolidin-2-yl)-1H-tetrazole ((S/R)-ptzH) ligand. Compound 1 exhibits good solvent stability and acid-base stability. Notably, 1 displays yellow room-temperature phosphorescence that can be visually observed for approximately 2 s, marking a significant milestone in MOFs incorporating proline-tetrazole ligands.
