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　metal-organic　frameworks　(MOFs)　incorporating　proline-tetrazole　ligand.
