title: Anion recognition by charge neutral electron-deficient arene receptors.
abstract: Anion-π interactions are newly emerging non-covalent interactions and have attracted considerable attention from both theoreticians and supramolecular chemists. This short review article summarizes the recent advances in anion recognition using charge neutral electron-deficient aromatic  compounds.
