Where is the radical? The π‐system of the diiminobenzene bridge adds a putative oxidation site to prophenoxyl copper(II) salophen complexes. It is shown that the bridge is effectively redox active and that the radical site (phenoxyl vs. diiminobenzene bridge) in the above cations is tuned by selective methoxy substitution (see figure).
