Abstract

Abstract : Trisamide tripodal derivatives act as low-molecular-weight gelators displaying different morphologies in the absence and presence of anions. Abstract : We report the syntheses and characterization of three isomers of trisamide tripodal derivatives. All these compounds act as low-molecular-weight gelators and the variation of the gel morphology with respect to the solvent combination has been analysed. The anion binding studies revealed that these tris-amide derivatives also act as suitable receptors for appropriate analytes. In this work, we have explored the role of geometry or extent of receptor–anion interaction on the gel architecture in the presence of anions such as F −, CN −, CH3 COO − and H2 PO4 − . We have discussed the anion responsive gel formation of one isomer after incorporation of anions in the solution phase as well as into the gel morphology.
