Covalent Organic Frameworks (COFs) Phenylacetylene Ligand

A rigid ethynyl functional ligand linker for COFs in application of photoluminescent probe, catalyst, fluoride detection and palladium scavenger

4,4'-Diethynyl-1,1'-biphenyl (DEBP) is a rigid linear biphenyl ligand with extended conjugation of ethynyl functional groups on both ends.

DEBP-BMOP, a Lewis acidic microporous organic polymer derived from tris(4-bromo-2,3,5,6-tetramethylphenyl)boron nodes and 4,4'-diethynyl-1,1'-biphenyl linkers with a pore size of 1.08 nm has been engaged in selective sensing and capture of fluoride ion. DEBP-BMOP showed selective turn-on blue emission for fluoride ions in aqueous mixtures with a detection limit of 2.6 μM. 

Porous polymeric metalloporphyrin [PoP(MTPP), M = Co, Mn], derived from metal complexes of (5,10,15,20-tetrakis(p-bromophenyl) porphyrin) (MT4BrPP) (M = Co, Mn) and 4,4'-diethynyl-1,1'-biphenyl as monomers by Sonogashira cross-coupling reaction served as a catalyst for the cycloaddition reaction of epoxides and CO2 to form cyclocarbonate with a high yield of 90%.
