Covalent organic frameworks (COFs) hexaphenylbenzene ligand

a C6 symmetric ligand for synthesising controllable microporous COFs

Specifications | MSDS | Literature and Reviews

Hexa(4-formylphenyl)benzene (CAS number 1862220-96-9) is a ligand featuring a hexaphenylbenzene core and six aldehyde groups. Hexa(4-formylphenyl)benzene is a C6 rotational symmetric ligand. This ligand is used in the construction of 2D COFs with various tiling topologies, including triangular, rhombille, and kagome, depending on the choice of linkers used in the reaction. The resulting 2D COFs have controllable pore sizes, offering short molecular diffusion length and facilitating host-guest interactions for drug delivery.

A COF with azine linkages can be prepared from hexa(4-formylphenyl)benzene and hydrazine. The resulting COF has high surface area exceeding 1200 m2/g, with an average pore size of 1 nm. It also demonstrates excellent performance of CO2 and methane uptakes, with capacities of 20 wt% and 2.3 wt%, respectively.
