Trinitroxide-Trioxytriphenylamine: Spin-State Conversion from Triradical Doublet to Diradical Cation Triplet by Oxidative Modulation of a π-Conjugated System
Spin‐state conversion: Oxidation of trinitroxide‐trioxytriphenylamine introduces extended π conjugation, resulting in a ground‐state spin conversion from the antiferromagnetic coupling in the neutral spin‐doublet state to the ferromagnetic coupling in the cation spin‐triplet state. The reversible conversion between the two states was confirmed by a change in the UV/Vis absorption under electrochemical
