Covalent Organic Frameworks (COFs) Terphenyl Ligand

An aldehyde fluoro functionalised bridging ligand linker for COFs in application of fluorescence probe, carbon dioxide capture, catalyst, and selective gas adsorption


1,3,5-Tris[(4-phenylboronic acid)]benzene (TPBAB) is a triangular with three phenyl boronic acid groups on the meta positions of the benzene ring. 1,3,5-Tris[(4-phenylboronic acid)]benzene is commonly engaged in the construction of the covalent organic frameworks via condensation reactions.

Microporous crystalline and mesoporous 2D covalent organic frameworks, COF-8, constructed from 1,3,5-tris[(4-phenylboronic acid)]benzene and 2,3,6,7,10,11-hexahydroxytriphenylene building blocks, showed great thermal stability, low density, and high porosity  with a surface areas of 1400 m2 g-1.

Obtained by condensation reaction using 2,3,6,7,14,15-hexaaminotriptycene and 1,3,5-tris[(4-phenylboronic acid)]benzene, highly porous diazaborole-linked polymer, DBLP-4,  exhibited high BET surface area of 904 m2 g−1 with potential application in small gas storage and separation. The amorphous polymers show high CO2 uptake of 4.5 mmol g−1 at 273 K with good CO2 selectivity over Nat ambient pressure.
