Covalent Organic Frameworks (COFs) Terphenyl Ligand

A formyl functional ligand linker for COFs in application of iodine uptake, photocatalytic hydrogen evolution (PHE), high-performance supercapacitors and heterogeneous catalysis

Specifications | MSDS | Literature and Reviews

1,2,4,5-Tetrakis(4-formylphenyl)benzene (TFPB), CAS number 883835-33-4, is a cross-like terphenyl linker with four 4-formylphenyl functional groups attached to a benzene ring at 1,2,4,5-positions.

Constructed by the condensation reaction between 2,5-diaminobenzene-1,4-dithiol (DABDT) and 1,2,4,5-tetrakis-(4-formylphenyl)benzene, thiol-decorated covalent organic framework SH-COF-2 showed a high surface area of 227 m2 g−1 and enhanced electrochemical performance with a capacitance of 118 mF cm−2 and a capacitance retention >95% after 1000 cycles.

Highly conjugated two-dimensional covalent organic framework TFPB-PyTTA-COF, alternating 4,4',4'',4'''-(pyrene-1,3,6,8-tetrayl)tetraaniline (PyTTA) as the nodes and 1,2,4,5-tetrakis(4-formylphenyl)benzene as the bridging linker units, possessed high chemical and physical stability. TFPB-PyTTA-COF exhibited an excellent iodine uptake value of up to 5.6 g g−1, superior to most reported COF-based adsorbents for the adsorption of iodine.

COF-TPE-TPB-B, obtained via a [4 + 2] pathway with unreacted dangling formyl groups from the monomers TFPB and 1,1,2,2-tetra(4-aminophenyl)ethylene (TPE-NH2), exhibited photocatalytic hydrogen evolution (PHE) activity with improved hydrophilicity and better charge separation and transportation.
