A cationic calix[4]arene derivative binds both aliphatic and aromatic, carboxylate and sulfonate anions inaqueous solution thanks to concerted electrostatic and hydrophobic interactions. The sulfonate guestinclusion is affected by the different mobility of the host caused by the pH change.

Abstract
A cationic calix[4]arene derivative binds both aliphatic and aromatic, carboxylate and sulfonate anions inaqueous solution thanks to concerted electrostatic and hydrophobic interactions. The sulfonate guestinclusion is affected by the different mobility of the host caused by the pH change.File in questo prodotto:
