The potential applications of self-assembled supramolecular gels based on natural molecules encouraged the researchers to develop a versatile synthetic method for their structural analogues. Herein, we report a facile synthesis of glycolipid from renewable resources, cashew nut shell liquid,d and d-glucose in good yield. Gelation behavior of these glycolipids were studied in a wide range of solvents and oils. To our delight, compound formed a hydrogel with Critical gelator concentration (CGC) of 0.29% /. Morphological analysis of the hydrogel depicts the formation of twisted fibers with an entangled network. Formation of a twisted fibrous structure was further identified by CD spectral studies with respect to temperature. The molecular self-assembly assisted by hydrogen bonding, hydrophobic, and π⁻π stacking interactions were identified by X-ray diffraction (XRD) and FTIR studies. Rheological analysis depicted the mechanical strength and stability of the hydrogel, which is crucial in predicting the practical applications of supramolecular soft materials.
基于天然分子的自组装超分子凝胶的潜在应用促使研究人员为其结构类似物开发一种通用的合成方法。在此，我们报道了一种从可再生资源腰果壳液和d-葡萄糖高产率地轻松合成糖脂的方法。研究了这些糖脂在多种溶剂和油中的凝胶化行为。令我们高兴的是，化合物形成了一种临界凝胶剂浓度（CGC）为0.29%/的水凝胶。水凝胶的形态分析描绘了具有缠结网络的扭曲纤维的形成。通过CD光谱研究进一步确定了扭曲纤维结构随温度的形成情况。通过X射线衍射（XRD）和傅里叶变换红外光谱（FTIR）研究确定了由氢键、疏水作用和π-π堆积相互作用辅助的分子自组装。流变学分析描述了水凝胶的机械强度和稳定性，这对于预测超分子软材料的实际应用至关重要。
