Sulfide oxidation tuning in 4,8-bis(5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b:4,5-b′]dithiophene based dual acceptor copolymers for highly efficient photocatalytic hydrogen evolution

A sulfide oxidation tuning approach in BDTT is reported for constructing a series of dual acceptor 1-2 (A 1 –A 2 )-type copolymers. PBDTTS-1SO achieved an outstanding HER, demonstrating that the immense potential of the A 1 -A 2 -type polymer photocatalysts.
