Metal Organic Frameworks (MOFs) Trigonal Terphenyl Ligand

A trigonal nanosized ligand linker for MOFs in applications of hydrogen adsorption

Specifications | MSDS | Literature and Reviews

1,3,5-Tris[4′-carboxy(1,1′-biphenyl-4-yl)]-benzene (H3TCBPB), CAS number 911818-75-2, a trigonal nanosized carboxylate ligand, has a biphenyl linker between the central phenyl ring and the carboxylic groups. The distance between two carboxylate groups is about 2 nm, and the distance between a carboxylate group and the central benzene ring is 1.2 nm.

As opposed to other carboxylic acid assemblies, dimers of H3TCBPB furnishes a deformed hexagonal porous network based on energetically inferior 2-fold C−H···O hydrogen bond, instead of 2-fold O−H···O hydrogen bonds as expected. This bonding pattern results in displaced dimers, instead of the much ordered head-to-head arrangement, which allow for higher packing density, and give rise to chiral polymorphs due to their lower symmetry.

MOF based on aluminum ion cluster nodes and H3TCBPB ligand linkers, titled as Al-TCBPB, with a monoclinic crystal structure and a space group c2/m, exhibits a high BET surface area of 2,311 m2/g and a total pore volume of 0.80 cm3/g. It shows an excess hydrogen adsorption of 4.8 and 1.4 wt.% at 9 MPa and 77 and 298 K, respectively.
