A new type of gelator with π?π stacking as weak interaction force was designed and synthesized. Pyromellitic acid esters were synthesized from pyromellitic dianhydride and alcohols of different carbon chain lengths to reduce hydrogen bonding sites.Then the gel capabilities were explored in common different organic solvents.The rheological test shows that the elastic modulus of the gel system is ten folds higher than the storage modulus,indicating that the gel has good mechanical properties and exhibits typical solid?like rheological behavior.Fourier transform infrared spectroscopy,nuclear magnetic resonance spectroscopy,scanning electron microscopy and DSC results show gelators formed fibrous self?assembled aggregates in gel under driving force from π?π stacking and the van der Waals force.The formed aggregates entangle with each other and finally form a three?dimensional network structure that hinders the flow of the solvent to form the gel.
