N,N′‑Bicarbazole-Based Covalent Triazine Frameworks as High-Performance Heterogeneous Photocatalysts
journal contribution

porous covalent triazine frameworks (CTFs, i.e., BC-CTF and Ph-BC-CTF)
were readily prepared by mild trifluoromethanesulfonic acid-catalyzed
synthesis. These two CTFs have comparable surface areas and chemical
constitutions with the ionothermal frameworks but feature less energy
penalty and better optical properties due to the avoidance of partial
carbonization at high temperatures. The two CTFs exhibit excellent
CO2 adsorption capacity thanks to the presence of nitrogen-rich
bicarbazole, triazine skeletons, and high surface areas. Furthermore,
BC-CTF and Ph-BC-CTF serve as highly efficient heterogeneous photocatalysts
for the degradation of rhodamine B and selective oxidation of thioanisoles
to sulfoxides under visible light.
