Driving chemical reactions with light

How can chemical reactions be triggered by light, following the example of photosynthesis in nature? This process is still poorly understood. However, researchers from Johannes Gutenberg University Mainz (JGU) in Germany und Rice University in Houston, USA, have now uncovered a major piece of the puzzle. Their findings have been published recently in Science Advances.
