Scientists have crafted novel macrocycles, composed of aromatic rings and amide bonds, that adeptly capture and transport anions. Their rigid structure compels hydrogen bond donors inward, forming a highly electropositive cavity ideal for anion binding. Moreover, these macrocycles can integrate into bio-membranes, facilitating anion transport across cell membranes. This breakthrough holds promise for treating conditions like cystic fibrosis, marked by faulty anion transport.
