Tunable cyano substituents in D–A conjugated polymers accessed via direct arylation for photocatalytic hydrogen production†
Abstract
2-Styrylthiophene-based donor–acceptor linear conjugated polymers with tunable cyano substituents are atom-economically obtained via direct C–H arylation for platinum-free photocatalytic hydrogen production, affording a HER of up to 9.79 mmol h−1 g−1.
