Two tripodal squaramide conjugates having 4-(trifluoromethyl)phenyl and 3,5-bis(trifluoromethyl)phenyl substituents were synthesized and found to exhibit highly efficient transmembrane anion transport with the EC50 values being 0.14 and 0.75mol%, respectively. Though one of them has been reported to act as a strong anion receptor, in particular for sulfate anions, these two compounds exhibit no significant selectivity with respect to the tested monovalent anions and a very low level of activity in the presence of sulfate anions.
