Metal Organic Frameworks (MOFs) Quaterphenyl Ligand

A linear ligand linker for MOFs in applications of artificial photosynthesis dyes, gas adsorption and separation, and catalysis


[1,1':4',1'':4'',1'''-Quaterphenyl]-4,4'''-dicarboxylic acid, also known as H2QPDC, is consisted of four phenyl rings joined linearly at 1,4-postions of each phenyl ring and two carboxyl groups (-COOH) at each end of the structure. With a hydrophobic body and hydrophilic heads, H2QPDC tends to form vertically self-assembled monolayers and Langmuir-Blodgett (LB) films.

The carboxyl group (-COOH) at both ends makes [1,1':4',1'':4'',1'''-Quaterphenyl]-4,4'''-dicarboxylic acid an ideal intermediate for the synthesis of metal organic framework (MOF) clusters as linkers. MOFs have shown great potential in various applications, such as heterogeneous catalysis, gas adsorption and separation, sensing, drug delivery, and artificial photosynthesis dyes etc. The unique physical and chemical properties of H2QPBC make it also a potential candidate for application in optoelectronic devices, such as bioelectronics and organic field-effect transistors (OFETs).
