A new hydrogelator based on L‐phenylalanine with a long hydrophobic chain and positivelycharged terminus was synthesized, and its gelation behavior in H2O was investigated. Polarized optical microscopy (POM), field emission scanning electron microscopy (FE‐SEM), and X‐ray diffraction (XRD) results indicate that the hydrogelator self‐assembles into fibres‐like aggregates which then lead to the formation
Organogels are used in a wide range of applications for which the development of new bio-based organogelators is highly desirable. While furan-2,5-dicarboxylic acid (FDCA) is a promising molecule for the synthesis of bio-based polyesters, it has never been used in the context of organogels. This study explores the possibility to design FDCA-based organogelators that self-assemble into fibrillar networks
有机凝胶具有广泛的应用,因此非常需要开发新型生物基有机凝胶剂。虽然呋喃-2,5-二甲酸 (FDCA) 是一种很有前景的生物基聚酯合成分子,但它从未用于有机凝胶。本研究探讨了设计基于 FDCA 的有机凝胶剂的可能性,该凝胶剂可自组装成通过氢键稳定的纤维网络。凝胶测试表明该凝胶剂系列具有多种凝胶液体(尤其是非极性液体)的多功能性。通过 FTIR 和 CD 光谱、晶体学、粉末 X 射线衍射和流变学研究了凝胶的结构。
