The article conveys some information:
Photoactive conjugated microporous polymers (CMPs) are emerging as porous materials capable of mediating the photocatalytic evolution of H2 from water. In this study, we synthesized three pyrene-based CMPs (Py-F-CMP, Py-TPA-CMP, Py-TPE-CMP) through Sonogashira-Hagihara cross-couplings of 1,3,6,8-tetraethynylpyrene (Py-T, as a common monomer building block) with 2,7-dibromo-9H-fluorene (F-Br2), tris(4-bromophenyl)amine (TPA-Br3), and 1,1,2,2-tetrakis(4-bromophenyl)ethene (TPE-Br4), resp., in the presence of Pd(PPh3)4 in DMF/Et3N. We then characterized the chem. structures, crystallinities, thermal stabilities, surface morphologies, and porosities of these three new CMPs. Brunauer-Emmett-Teller (BET) analyses and tests of photocatalytic H2 production revealed that Py-TPA-CMP displayed the highest BET surface area (454 m2 g-1), highest total pore volume (0.28 cm3 g-1), highest H2 evolution rate (19 200 μmol h-1 g-1), and highest apparent quantum yield (15.3%) when compared with those of Py-F-CMP, Py-TPE-CMP, and other organic porous materials.
