Cunning metal core: efficiency/stability dilemma in metallated porphyrin based light-emitting electrochemical cells

The syntheses, photophysical/electrochemical characterizations of different metallated porphyrins i.e. , Zn 2+ , Pt 2+ , Pd 2+ , and Sn 4+ porphyrins as well as their first application in light-emitting electrochemical cells are provided. A direct comparison demonstrates that depending on the metallation either efficient (Pt-por) or stable (Zn-por) devices are achieved, demonstrating that the choice of the metal core is a key aspect for future developments. The syntheses, the photophysical/electrochemical characterization, and the first application in LECs of different metallated porphyrins are provided.
