Recent developments in CO2 capture/storage/utilization with aromatic macrocycles

Abstract

Aromatic units bring special features to supramolecular receptors when the challenge of binding and release of CO2 is being addressed. Recent examples arising from calixarenes, pillararenes and cyclophanes are discussed in this review. The abilities of these systems to spatially organize metal coordination, hydrogen bonding or hydrophobic interactions for the purpose of CO2 binding are pointed out. Consequences for sensing and catalytic reactions are also highlighted.
