Conjugated microporous polymers (CMPs) are promising light harvesters for photocatalytic H2 evolution because they are simple to prepare with various band gaps. To achieve CMPs displaying high photocatalytic performance, appropriate building blocks must be chosen. We prepared four kinds of triphenylpyridine-based CMPs (TPP-CMPs) through reactions with multibrominated monomers having different geometries [1,3,6,8-tetrabromopyrene (pyrene-4Br), tris(4-bromophenyl)amine (TPA-3Br), 2,4,6-tris(4-bromrophenyl)pyridine (TPP-3Br), and 1,2,4,5-tetrabromobenzene (BZ-4Br), forming the TPP-pyrene (Py), TPP-triphenylamine (TPA), TPP-TPP, and TPP-benzene (BZ) CMPs, resp.]. This strategy allowed effective synthetic regulation of electron enrichment, porosities, and optoelectronic properties of the TPP-CMPs. The surface areas of the TPP-CMPs were high, up to 1370 m2 g-1, and had a high thermal stability. TPP-Py CMP displayed the highest photocatalytic performance with a H2 production rate of 18 100 μmol g-1 h-1 under irradiation with visible light. Moreover, we achieved apparent quantum yields as high as 22.97% at 420 nm, comparable with those of most other CMPs reported previously. The experimental process involved the reaction of Tris(4-bromophenyl)amine(cas: 4316-58-9Application of 4316-58-9)
In general, Tris(4-bromophenyl)amine(cas: 4316-58-9) is often used in the synthesis of porous luminescent covalent–organic polymers (COPs)Application of 4316-58-9
