摘要: Six oligoamides with the same backbone but different side and end chains, G1–G6, were designed synthesized. Screening gelating abilities of these revealed G2 as a versatile gelator capable forming stable hydrogels well several organogels. From UV, fluorescence, NMR, SEM studies, formation is driven by hydrophobic forces π–π stacking while gelation nonpolar organic solvents relies on hydrogen-bonding interactions. The hydrogel able to encapsulate release medicinally important polar substances into water acid-responsiveness.
