Investigation of Dipyrrin Ligands for the Activation of Oxygen

Dipyrrin is an organic scaffold with the potential to form metal complexes. These complexes are explored for oxygen activation for uses in fuel cells or photodynamic therapy. In this research, dipyrrin was synthesized and coordinated with various metals to investigate its photochemical and electrochemical properties.
