1,3,5-Tris(4-hydroxyphenyl)benzene (THPB, CAS 15797-52-1) from Ossila is a triphenylbenzene monomer carrying three hydroxyl groups, supplied as a beige powder with purity above 98%. Its reactive hydroxyl groups make it a convenient building block for cross-linked porous networks such as covalent organic frameworks (COFs) and metal-organic frameworks (MOFs).
Combined with di(pyridin-2-yl) terephthalate, this ligand forms ester-linked COFs with hcb topology and surface areas reaching 2092 m2/g. It can also assemble bottom-up into hydrogen-bonded organic frameworks; DFT calculations indicate that the planar molecules connect through H-O hydrogen bonds between their hydroxyl groups.
Beyond porous materials, the compound serves as a core for triphenylbenzene-based carbazole macromolecules. These photoluminescent products show two strong bands at 353 and 369 nm, pointing to potential use in OLEDs.
