A glycol side-chain in conjugated polymer has water wettability for high hydrogen evolution in water-splitting photocatalysts. We synthesized Benzothiadiazole based polymer with glycol side chain which is synthesized acceptor moiety. With glycol side chain tuning polymers, we demonstrate the effect of polymer crystallinity on the hydrogen evolution of polymers. In this work, the role of backbone structure of conjugated polymer was investigated using comparing the alkyl side chain and glycol side chain. Furthermore, fluorinated donor moiety showed enhanced stability in polymer photocatalysts. To investigate the effect of these roles of structure to hydrogen efficiency, we performed that dielectric constants, OFET, TCSPC, μs-TAS, AQY, and hydrogen evolution rate tests.
