Exceedingly large , planar porphyrin systems composed of 49 non‐hydrogen nuclei in highly delocalized π systems display exceptionally low‐energy transitions in UV/Vis/NIR spectroscopy and in cyclic voltammetry. The spectra shown are for cis palladium complex depicted and the corresponding trans isomer
