We describe the preparation and characterization of two new unsym. squaramide-based organogelators. The synthesis of the compounds was carried out by subsequent amine condensations starting from di-Me squarate. The design of the gelators involved a squaramide core connected on one side to a long aliphatic chain and on the other side to a glutamic acid residue. The gelator bearing the free carboxylic groups showed a lower gelation capacity than its precursor diester derivative Some selected gels were further studied by IR spectroscopy, rheol. and electron microscopy. Critical gelation concentrations and gel-to-sol transition temperatures were also determined for each case. In addition, the superior squaramide diester gelator was compared with an analog triazole-based gelator in terms of critical gelation concentration, gelation kinetics and thermal phase transition.
