In this Feature Article, we discuss the design strategy, syntheses, and the self-assembly of various sugar-based gelators to form organogels. We illustrate the use of organogels formed by these sugar-based gelators for various applications such as (a) development of scratch-free, shatter-free, soft-optical devices using oil gels formed by mannitol-based gelators, (b) marine oil-spill recovery using sugar-based phase selective organogelators, (c) preparation of semiconducting cotton cloths using a diyne functionalized sugar gelator, (d) development of sugar arrays on glass slides using a polymerizable diyne functionalized sugar gelator for efficient lectin binding, (e) development of sintering resistant hybrid CaO-silica material for the absorption of CO, (f) preparation of porous polystyrene-crown ether matrix for the selective alkali metal ions sequestration, and (g) preparation of porous polystyrene, structured silica, and fluorescent gels using a library of sugar-based gelators, and also the mechanism of gelation of some of these gelators have been discussed. We have also given our perspective toward exploring sugar-based gelators for advanced applications.
在这篇专题文章中，我们讨论了设计策略、合成以及各种基于糖的凝胶剂的自组装，以形成有机凝胶。我们举例说明了这些基于糖的凝胶剂所形成的有机凝胶在各种应用中的用途，如(a) 使用甘露醇基凝胶剂形成的油凝胶开发无划痕、无碎裂、软光学器件，(b) 利用基于糖的相选择性有机凝胶剂进行海洋溢油回收，(c) 使用二炔官能化糖凝胶剂制备半导体棉织物，(d) 使用可聚合二炔官能化糖凝胶剂在玻璃载玻片上制备糖阵列以有效结合凝集素，(e) 制备抗烧结的混合 CaO-二氧化硅材料以吸收 CO，(f) 制备用于选择性捕获碱金属离子的多孔聚苯乙烯-冠醚基质，以及(g) 使用一系列基于糖的凝胶剂制备多孔聚苯乙烯、结构化二氧化硅和荧光凝胶，并且还讨论了其中一些凝胶剂的凝胶形成机制。我们还对探索基于糖的凝胶剂用于高级应用提出了我们的看法。
