The preparation and characterization of two π-cation radical derivatives of copper β-oxoporphyrins is described. [3,3,8,8,13,13,17,18-octaethyl-(3H,8H,13H)-porphine-2,7,12-trionato (2-)] copper π-cation radical, [ Cu (2,7,12-trioxoOEHP·)]+, and [3,3,8,8,12,13,17,18-octaethyl-(3H,8H)-porphine-2,7-dionato(2-)] copper π-cation radical, [ Cu (2,7-dioxoOEiBC·)]+, have been prepared and characterized by single-crystal X-ray determinations, UV/vis/NIR, and IR spectroscopies. Both molecules have modest distortion from the planarity and show monomeric units in the solid state. [ Cu (2,7-dioxoOEiBC·)]+ shows a concentration dependent near-IR band at 1410 nm.
