Long lifetime photoluminescence emission of 3D cadmium metal–organic frameworks based on the 5-(4-pyridyl)tetrazole ligand

• New metal–organic frameworks based on 5-(4-pyridyl)tetrazole.
• Hydrothermal syntheses reveal new possibilities to rational formation on MOFs.
• Cadmium MOFs exhibit blue-green long lifetime photoluminescence.
• Theoretical studies about pore size distribution and experimental gas adsorption.

Three new metal–organic frameworks based on 5-(4-pyridyl)tetrazole have been synthesized by hydrothermal routes mixing this linker with cadmium(II) chloride in the presence of secondary ligands such as squaric acid, 4-carboxypyridine and terephthalic acid in water. Hydrothermal syntheses reveal new possibilities to rational formation on MOFs by mixtures of different linkers using the appropriate stoichiometry. These polymers exhibit blue-green photoluminescence emission at room temperature in the solid state with long lifetime decays. Theoretical studies about pore size distribution and experimental gas adsorption studies have also been included.
