Abstract Functional gels from self-assembled macrocyclic host molecules towards diversified applications are promising yet challenging. In this work, we report a novel protocol to build up organogel materials via the delicate solvent balance. By utilization of good/poor solvent or nanoprecipitation method, self-assembly of β-cyclodextrin with abundant hydrogen bonding sites were triggered, generating sheet-like structures at microscale. The gels exhibit fine colloidal stability, robust mechanical strength and thermo-resistance properties, which can also be regulated by varying poor solvent (alcohols) compositions. Also, the polar organic solvent systems as well as the intrinsic micro/nanopockets among sheet structures provided space for entrapping fluorescent dyes. Due to the excellent properties of the gels, we successfully applied the gels as vessel supporting materials.

利用溶剂平衡制备大环有机凝胶及其在血管支持材料中的应用

摘要 从自组装大环宿主分子到多样化应用的功能凝胶是有前途的，但具有挑战性。在这项工作中，我们报告了一种通过微妙的溶剂平衡来构建有机凝胶材料的新协议。通过利用良/差溶剂或纳米沉淀方法，触发了具有丰富氢键位点的 β-环糊精的自组装，在微米尺度上产生片状结构。凝胶表现出良好的胶体稳定性、强大的机械强度和耐热性能，这也可以通过不同的不良溶剂（醇类）组成进行调节。此外，极性有机溶剂系统以及片状结构之间固有的微/纳米袋为捕获荧光染料提供了空间。由于凝胶的优良特性，
