1,3,5-Triazine and Dibenzo[b,d]thiophene Sulfone Based Conjugated Porous Polymers for Highly Efficient Photocatalytic Hydrogen Evolution

Organic conjugated porous polymers , Triazine-Ph-CPP and Triazine-Th-CPP, are synthesized and characterized. Without further addition of co-catalysts, Triazine-Ph-CPP exhibits a HER of 16287 μmol g-1h-1 and an apparent quantum yield of 61.5% at 365 nm, which demonstrates dibenzo[b,d]thiophene sulfone and 1,3,5-triazine based polymer is an unique prototype of highly efficient hydrogen evolution photocatalyst.
