Caption
The illustration shows a newly designed hexavalent covalent organic framework (COF) material that mimics photosynthesis.
(Left) Light triggers the transfer of an electron from a donor site to an acceptor site within the material (indicated by red arrows). This process transfers four positive charges to the donor site, which are then used to split water molecules into oxygen (indicated by green arrows). At the acceptor site, two electrons combine with oxygen to produce hydrogen peroxide (indicated by blue arrow).
(Right) The structure of the material allows for efficient movement of electrons (shown in yellow), positive charges (shown in blue), water, and oxygen throughout the single layer. This material has the potential to convert light energy into chemical energy in a similar way to natural photosynthesis.
