A homogeneous system for photogeneration of hydrogen initiated by bodipy based photoinduced electron transfer

Abstract

The key technology to fulfill the energy needs in the future is the generation of fuels by harvesting solar energy. Due to high abundance and low prices of cobalt, water-splitting (based on cobalt) method has received a lot of attention compared to noble metals. Several times cobaltoxime based catalysts were studied for proton reduction. In this project, our aim was to produce a homogeneous photocatalytic system for photogeneration of hydrogen with high efficiency. To do so, we synthesized ten integrated molecules in which we are making use of the highly quantum efficient and photostable BODIPY chromophore. After the synthesis and characterization of target molecules, we achieved to demonstrate hydrogen evolution with five of our molecules.
