Abstract:
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.
