Stabilizing the Hexacyanotrimethylenecyclopropane Electron Acceptor—Structural and Photophysical Characterization

open access: yesAngewandte Chemie International Edition, EarlyView.
An improved low‐temperature synthesis enables the first comprehensive structural and spectroscopic characterisation of neutral hexacyanotrimethylenecyclopropane (CN6CP). Combined IR/Raman, UV–Vis and ssNMR analyses reveal a deeper understanding of its oxidation‐state‐dependent charge redistribution, σ‐aromaticity of the cyclopropane core, and redox ...
