• Anion binding
• Resorcin[4]arene
• Urea
• Carboxylate anion

Cavitand-based anion receptors were developed by the introduction of four phenylurea moieties on the upper rim of a resorcin[4]arene. Their binding properties for various anions were investigated in DMSO-d(6) using (1)H NMR spectroscopic methods, and the high 1:1 binding affinity for carboxylates was observed due to hydrophobic as well as charge-dipole interactions between host and guest.
