A family of acyclic squaramide receptors (L1-L5) have been synthesised with the aim to bind anions in a competitive solvent mixture and to evaluate how the presence of additional H-bond donor groups on the squaramide scaffold could affect the affinity towards anions and the transmembrane transport ability.
