Recently, Hillman et al. investigated the importance of sulfone units normally used in some polymers on photocatalytic hydrogen production and found that sulfone units play important roles in light absorption; hole transfer to triethylamine (TEA) SD, and electron transfer to residual Palladium . Benzothiadiazole (BT) unit is also a common acceptor used in polymers that have shown good photocatalytic performance . Recently, we have shown that a BT analogue benzothiadiazole dicarbonitrile (BTDN) could generate hydrogen on a glassy carbon electrode during the electrocatalytic conditions and the protonated intermediate species were studied
