Covalent Organic Frameworks (COFs) Terphenyl Ligand

An aldehyde fluoro functionalised bridging ligand linker for COFs in application of fluorescence probe sensors, membrane, and detection of dopamine


Specifications | MSDS | Literature and Reviews


Trigonal 1,3,5-tris(3-fluoro-4-formylphenyl)benzene (TFFPB), CAS number 2088007-04-7, has a chemical structure of three 3-fluoro-4-formylphenyl groups sitting at the meta positions of a benzene ring. The aldehyde groups help to extend the structure to frameworks by forming covalent bonding and the fluoro-groups enhance the richness of the fluorine content of the targeted structures.

Constructed from 1,3,5-tris(4-aminophenyl) benzene (TPB) and 1,3,5-tri(3-fluoro-4-formylphenyl) benzene as the building elements at room temperature, porous covalent organic framework TPTF-COF is fluorine-rich, highly crystalline and thermally stable with rich functional group properties and large specific surface area of 1084.61 m2·g−1.

Containing 1,3,5-tris(3-fluoro-4-formylphenyl)benzene nodes and acrylonitrile linkages, smart COF showed rapid pH-responsive absorption and fluorescence, high fluorescence quantum yield, and good crystallinity. It exhibited a 20% enhancement in fluorescence quantum yield and more rapid sensitivity of absorption and fluorescence under acid–base induction compared to its nonfluorinated counterpart.
