Macrocyclic weakly coordinating anions

Abstract

Herein, the concept of macrocyclic weakly coordinating anions (M-WCAs) is introduced. Synthetic methodologies are described how to access M-WCAs by thermodynamically controlled self-assembly in high yields, in particular through condensation and alkyne metathesis reactions. The anticipated properties and applications of M-WCAs in solid state and in solution are discussed, specifically for gas storage and separation, homogeneous and heterogeneous catalysis, and as liquid and solid electrolytes.

Keywords: catalysis; gas adsorption; macrocycles; nanoporosity; weakly coordinating anions.
