Chemists from the University of Würzburg and Yonsei University have developed a stack of four perylene bisimide dyes that closely mimics the photosynthetic apparatus of plants. This innovation represents a significant advancement in artificial photosynthesis, allowing for the efficient absorption of light energy, separation of charge carriers, and their rapid transfer through the dye stack. The ability to imitate photosynthesis could enable the conversion of solar energy into useful substances, such as carbohydrates and hydrogen, by utilizing carbon dioxide and water. The research team, led by Professor Frank Würthner, aims to expand this system to create a supramolecular wire that can transport light energy over longer distances, further enhancing the potential for artificial photosynthesis. The findings have been published in the journal Nature Chemistry.

1 commentsIt's my non-scientific theory (and it is mine) that energy centric physical chemistry like this converting solar and other light sources into something tractable in another form of energy, which depends on quantum states coming in and out inevitably also depends on somewhat unstable compounds and atomic states. It's hardly surprising the "efficient" ones also tend to break down the reactants, and I would imagine even in a plant there is a process behind making Chlorophyll rich cells stable, and renew.
