The intricate world of advanced materials like Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) is built upon the precise arrangement of molecular components. At the heart of these structures are organic linkers, molecules that bridge metal ions or organic units to form extended, often porous, networks. Understanding the chemistry of these linkers is crucial for anyone involved in their synthesis and application.

[3-(4-Carboxyphenyl)phenyl]benzoic acid (CAS 13215-72-0) stands out as a particularly interesting and useful organic linker. Its molecular structure, characterized by a terphenyl core with carboxylic acid groups positioned at the terminal ends of the outer phenyl rings, imparts specific geometric and electronic properties. The terphenyl backbone offers rigidity and a defined spatial orientation, while the two carboxylic acid functionalities provide the reactive sites for coordination with metal centers in MOFs or for covalent bond formation in COFs.

The presence of two carboxylic acid groups makes it a dicarboxylic linker, capable of forming extended polymeric structures. Its molecular formula, C20H14O4, and molecular weight of 318.32 g/mol are fundamental parameters that chemists consider when designing synthetic strategies. The physical appearance of this compound is typically a white to off-white solid, indicating its stability under ambient conditions.

In the context of MOF synthesis, the carboxylic acid groups readily deprotonate to form carboxylates, which then coordinate with metal ions or clusters. The precise angle and distance between these coordination sites, dictated by the terphenyl geometry, directly influence the topology and pore dimensions of the resulting MOF. This makes [3-(4-carboxyphenyl)phenyl]benzoic acid a valuable tool for constructing frameworks with targeted porosity for applications such as gas storage and separation.

For researchers and manufacturers looking to buy this essential linker, sourcing from reputable chemical suppliers is key.
