Metal Organic Frameworks (MOFs) Triphenylpyridyl Ligand

A triangular ligand linker for MOFs in applications of iron detection, carbon dioxide fixation and catalytic reactions


2,4,6-Tris-(p-carboxyphenyl)pyrdin (H3PTB) ias a pyridine-based tritopic linker with three 4-carboxyphenyl groups at 2,4,6-positions of the central pyridine ring.

Luminescent MOF PCN‐604, based on 2,4,6-tris-(p-carboxyphenyl)pyrdin as the ligand linkers and aluminum ion cluster nodes, shows excellent thermal and chemical stability. As a luminescent senor, PCN‐604 shows intense luminescence in water and promising sensitivity and selectivity towards trace amount of Fe3+ ions with quenching constant of 2.85 x 104 M‐1 and low detection limit of 6.2 μM.

Crystalline framework, [Cu3(H3PTB)2(H2O)3]n, is mesoporous in nature and it is showing dual functionality in the removal of organic dyes. Microporous Zn-H3PTB based anionic MOF shows open channels capturing the cationic dye methylene blue. The Zn-MOF also demonstrates excellent catalytic activity for CO2 fixation by cycloaddition reaction with epoxides for the generation of cyclic carbonates.
