Clarifying the electron transfer pathway of organic photocatalyst for hydrogen evolution

Elucidating the mechanism of electron transfer poses a significant challenge in the exploration of organic semiconductor photocatalysts. In a recent publication in Chem, Zhong and colleagues disclosed findings on a small molecular, metal-free photocatalyst featuring a pyrene core as the electron donor and pyridine as the electron acceptor. Through a comparative analysis involving a series of control samples, they meticulously traced the electron transfer pathway.
