It has been recognized that those are not conventional p/n type semiconducting junction devices, but are so called donor-acceptor (D A) photocells, reminiscent of reaction centers of natural ...

This ESPT reaction involves a proton relay from the phenol hydroxyl of the chromophore ... recent high-resolution structural data in which the distance between the donor and acceptor oxygen atoms is ...

In this regard, electron-donor–acceptor (EDA)-complex reactions have emerged as a powerful strategy in organic synthesis, eliminating the need for photocatalysts under visible light irradiation.
