Covalent Organic Frameworks (COFs) Quinquephenyl Ligand

A trigonal ligand linker for covalent polymeric frameworks (CPFs) in application of nitrofurazone detection and photocatalyst


Specifications | MSDS | Literature and Reviews


1,3,5-Tris[4-amino(1,1-biphenyl-4-yl)]benzene (TABPB) is a trigonal hexaphenylbenzene derivative with three 4-amino-[1,1'-biphenyl] units sitting at meta positions to each other on a benzene ring. TABPB has a suitable aromatic skeleton in which slight distortion between phenyl groups reduces aggregation-induced quenching.

2D Donor–acceptor metal–organic framework JNM-18 with alternating units of Cu(I) cyclic trinuclear as an electron acceptor and 1,3,5-tris[4-amino(1,1-biphenyl-4-yl)]benzene as an electron donor, shows efficient photocatalytic activity for the aerobic oxidation reaction of benzylamines upon irradiation with a violet LED. Also, COF with imine linkers from Schiff condensation of 2,5-dihydroxybenzaldehyde and 1,3,5-tris[4-amino(1,1-biphenyl-4-yl)]benzene shows strong fluorescence with a strong emission peak at 408 nm for nitrofurazone detection. The detection range is 0.066–39 µg mL−1 with a detection limit of 0.022 µg mL−1.
