MB-DIPY-based stable radicals with redox-switchable absorption beyond 1000 nm have been prepared and characterized by spectroscopic and theoretical methods. Stable radical complexes can be either oxidized to regular [MII(MB-DIPY)]+ (M=Cu or Ni) or reduced to [MII(MB-DIPY)]- compounds within an ∼400 mV electrochemical window.
