To achieve hydrogen generation with earth-abundant materials and nature light is one of the best solution to solve the environment problem and energy crisis in front of us. Here we introduce a water-soluble conjugated polymer polythiophene derivative as photosensitizer to the photo-induced hydrogen generation system, in which hydrogen can be produced under both Xenon lamp and nature light. “Turn-off” and “turn-on” of the hydrogen generation have also been explored. A supromolecular self-assembly swith was introduced in our system, for the supramolecular assembly and dis-assembly of one electron recduced methy viologen with cucurbit[8]uril (CB[8]) regulates the electron transfer between the methy viologen radical and catalyst Pt, which results in the turn off and turn on of the hydrogen generation.
