Mixtures of alkylamide derivatives with different alkyl chains were found to form organogels which exhibit thixotropic properties, while single alkylamide components formed organogels which did not exhibit such properties. With a three-component alkylamide system, the transparency and mechanical properties (toughness and stimulus-responsiveness) of the resulting organogels were enhanced. This mixing enhancement for organogelators may be due to the improved network density compared with that of the one-component systems.
