Luminescent dipyrrinato complexes of d-block metals are well explored in literature for diverse applications in materials as well as in biology. They offer exceptional fine tuning of their electrochemical and optical properties with the variety of substitutions on the dipyrrin core. The development of mixed ligand type dipyrrinato complexes with heavy metals like: Ru, Os, Pd, Pt, Re, Ir are of great interest in biomedical applications due to significant ROS (Reactive Oxygen Species) generation, anti-microbial and anti-cancer applications. Such dipyrrinato complexes display bright triplet emission in the visible to red region due to heavy atom effect.
