Biphenyl-4,4'-dicarboxylic acid, 98%

Product Introduction

Biphenyl-4,4'-dicarboxylic acid is a rigid, linear aromatic dicarboxylic acid that can function as a bifunctional organic building block and coordination linker.

The two carboxylic acid groups can coordinate with metal ions or metal clusters, while the biphenyl structure provides a relatively rigid aromatic framework. These characteristics make the compound particularly relevant to the synthesis and investigation of MOFs and other coordination polymers.

It can also be investigated as a monomer or functional building block for polymeric and supramolecular materials where rigidity, aromaticity, and carboxyl functionality are desirable. TCI specifically identifies this compound as an organic linker molecule for MOF research.

Mechanism / Principle

The primary chemical functionality of Biphenyl-4,4'-dicarboxylic acid comes from its two carboxylic acid groups.

In coordination chemistry, the carboxylate groups can interact with metal ions or metal clusters to form coordination bonds. Because the two carboxyl groups are positioned on opposite ends of a relatively rigid biphenyl backbone, the molecule can serve as a bridging ligand during the construction of extended coordination networks.

In MOF synthesis, this linker functionality can contribute to the formation of multidimensional metal-organic frameworks. The aromatic backbone can also influence framework rigidity, pore structure, and chemical environment.
