Donor–acceptor engineering in conjugated polymer photocatalysts: thieno[3, 2- <i>b</i> ]thiophene-dibenzothiophene sulfone copolymers for noble-metal-free visible-light hydrogen evolution
Extending the oligothiophene linkers (T → DT → TT) in the D–A polymer TPA-BTDO enhances H 2 evolution by improving coplanarity and reducing charge recombination, with TPA-TT-BTDO achieving HER rates of 101.2 (visible) and 125 mmol h −1 g −1 (sunlight).
