Binary organogels based on glutamic acid derivatives and different acids: Solvent effect and molecular skeletons on self-assembly and nanostructures

In this paper new binary organogels based on glutamic acid derivatives and acids with different molecular skeletons were designed and prepared. Their gelation behaviors in single or mixed solvents were tested as novel low-molecular-mass organic gelators. The experimental data showed that the solvents and molecular skeletons played a crucial role in regulating the gelation behaviors and fabrication of nanostructures. Suitable single solvents or volume ratios in ethanol/water mixed solvents seemed more favorable for the formation of supramolecular gels due to cooperation of multi-intermolecular weak forces. Rational assembly modes in organogels were proposed and discussed. The present work may give some insight to design and character new versatile organogelators and soft materials with special molecular structures.
