Supramolecular anion recognition by tetrapyrrolic macrocycles

Abstract

Anions represent one of the most important species in the natural world and are involved in many crucial chemical processes. Anion coordination chemistry highlights the complexity and importance of anion recognition in almost conceivable biochemical and environmental chemistry processes. This mini review is intended to present recent results achieved in this field, mainly by calix[4]pyrroles and porphyrins. The synthesis and their ability to interact with anionic species will be discussed.
