Purely Organic Mixed‐Valence Molecules with Nanometric Dimensions Showing Long‐Range Electron Transfer. Synthesis, and Optical and EPR Studies of a Radical Anion Derived from a Bis(triarylmethyl)Diradical

Both optical and thermal electron transfer were examined in detail in radical anion 1, which was generated electrochemically from the analogous stable diradical. Optical electron transfer is induced at λ = 1400 nm. The results are discussed in the context of the Hush-Marcus theory.
