Metal Organic Frameworks (MOFs) Dipyridylbenzene Ligand

A rigid linear ligand linker for MOFs in applications of environmental protection and separation of the isomers


1,4-Di(4-pyridyl)benzene (DPyBz) has two end 4-pyridine units joined by a benzene ring at 1,4-positions.

Highly porous metal–organic framework Zn2(TCPP)(DPyBz) (H4TCPP = 2,3,5,6-tetrakis(4-carboxyphenyl)pyrazine) has permanent porosity with high BET areas 1,324 m2 g−1. The Zn2(COO)4 paddlewheel units of the metal-organic framework are fitted together by the TCPP4− ligands to form two-dimensional layers and then further connected by DPyBz ligands as pillars to construct a two-fold catenated 3D framework. Zn2(TCPP)(DPyBz) shows selective CO2 and light hydrocarbon capture with potential applications for environmental protection.

Metallacycle iridium complex, also bearing 1,4-di(4-pyridyl)benzene, can produce n-hexane with a purity of >99% in a single adsorption–desorption cycle from an equimolar mixture of all five isomers of hexane, taking advantage of these dihydrogen bond interactions (B–Hδ−···Hδ+–C ) for the separation of the isomers.
