Abstract

Intense colorations and new charge-transfer absorption bands are observed upon addition of a halide (Cl⁻, Br⁻, I⁻) to neutral organic π acceptors with electron-deficient olefinic and aromatic centers. These phenomena results from noncovalent anion–π interactions (shown schematically), which were confirmed by X-ray crystallography.
