Stimuli-Responsive Designer Supramolecular Polymer Gel

This paper reports a stimuli-responsive designer supramolecular polymer gel in dimethylsulphoxide (DMSO)/water (1:2) based on dipeptide amphiphile and β-cyclodextrin (β-CD) The contains caproic acid at the N terminus methyl ester C terminus. From X-ray single crystal diffraction, adopts kink-like conformation. self-assembled to form parallel sheet-like structure stabilized by multiple intermolecular hydrogen bonds. Moreover, is also edge-to-edge π–π stacking interactions. In higher-order packing, it forms corrugated hydrophobic interacts with through formation simple heating-cooling cycle. sol-to-gel transformation because of host–guest complex between compound 1 β-CD accompanied microstructure changes from nanofibers microrods. temperature responsive Tgel 70 °C. stimuli such aspicric HCl. extensive spectroscopic studies show that aromatic side chain β-CD. These results will be helpful for design advanced programable eco-friendly functional materials.
