Conceived in theory and confirmed experimentally, anion�p interactions have emerged as a new paradigm of anion-recognition chemistry. Yet, after a decade since its inception, actual mechanisms of anion�p interactions remain highly debated. In this presentation, I will demonstrate how modes of interactions between anions and p-acidic naphthalenediimides (NDIs) can be varied from extremely weak nonchromogenic anion�p interactions to chromogenic anion-induced charge transfer (CT) and electron transfer (ET) phenomena by adjusting the electron-donating and accepting abilities of anions and NDIs, respectively. Anion-induced thermal and light-gated ET to NDIs generates colorful NDI�� radical anions and NDI2� dianions, which could be expolited for anion sensing and finger-printing, radical reactions, artificial photosynthesis, as well as molecular electronics and magnetism.
