描述了合成用于RP-HPLC的双烷基化L-谷氨酰胺衍生的固定相的新方法。TEM对脂质二硬脂基谷氨酰胺(DSG)的观察表明,通过酰胺基团之间的分子间氢键在甲醇或氯仿中形成了纤维状聚集体,而二丁基谷氨酰胺(DBG)由于其较短的烷基短链而无法在水性或有机介质中聚集。DSG和DBG通过氨基-丙基键与二氧化硅共价键合。已经发现附着于二氧化硅表面的脂质膜类似物(例如DSG)处于非晶态和固态状态,并且可以基于其在水性介质和有机介质中的高度有序结构而形成具有特定性质的超分子组装体。13 C CP / MAS NMR和悬浮液(在甲醇中)状态的1 H NMR,元素分析,用DSC和DSC测量来表征Sil-DSG,并与其他三个十八烷基相进行比较,即单体C18,聚合物C18和二氧化硅接枝的聚丙烯酸十八烷基酯Sil-ODA25。使用平面和非平面聚芳烃(PAHs)和非极性芳族位置异构体的详细保留研究,研究了新型RP材料

dual‐functional metallogel, which was based on the copper(II) complex of quinolinol‐substituted L‐glutamide, showed both redox‐responsive and enantioselective properties; moreover, the metallogels collapsed into a sol after reduction and could be revived upon subsequent oxidation. The supramolecular chirality and morphology also reversible changed with the gel–sol transition. Furthermore, the metallogels showed

emission and circular dichroism signals can be detected from the supramolecular gels formed by amphiphilic Schiff bases, none of them exhibits a circularlypolarizedluminescence (CPL). Although Mg2+, Zn2+, and Al3+ can significantly enhance the fluorescence of the Schiff bases, interestingly, only Al3+ ion is able to turn on the CPL emission. This study on the one hand provides a simple method for the
A chiral amino acid functionalized probe, PTZ-D, could self-assemble into a chiral organogel displaying unprecedented chiroptical monitoring of ClO− with switchable CPL signals.
