| 英文摘要 | New amphiphilic gelators that contained both Schiff base and L-glutamide moieties, abbreviated as o-SLG and p-SLG, were synthesized and their self-assembly in various organic solvents in the absence and presence of metal ions was investigated. Gelation test revealed that o-SLG formed a thermotropic gel in many organic solvents, whilst p-SLG did not. When metal ions, such as Cu2+, Zn2+, Mg2+, Ni2+, were added, different behaviors were observed. The addition of Cu2+ induced p-SLG to from an organogel. In the case of o-SLG, the addition of Cu2+ and Mg2+ ions maintained the gelating ability of the compound, whilst Zn2+ and Ni2+ ions destroyed the gel. In addition, the introduction of Cu2+ ions caused the nanofiber gel to perform a chiral twist, whilst the Mg2+ ions enhanced the fluorescence of the gel. More interestingly, the Mg2+-ion-mediated organogel showed differences in the fluorescence quenching by D- and L-tartaric acid, thus showing a chiral recognition ability. |
