are key enzymes in metabolism, pathogenic/antipathogenic mechanisms and normal cellular functions. Recently, a novel approach for glycosidase inhibition that conveys multivalent glycomimetic conjugates has emerged. Many questions regarding the mechanism(s) of multivalent enzyme inhibition remain unanswered. Herein we report the synthesis of a collection of novel homo‐ and heterovalent glyco(mimetic)‐fullerenes

followed for the synthesis of a series of fullerene–ionic‐liquid (IL) hybrids in which the number of IL moieties (two or twelve), anion, and cation have been varied. The combination of C60 and IL give rise to new unique properties in the conjugates such as solubility in water, which was higher than 800 mg mL−1 in several cases. In addition, one of the C60–IL hybrids has been employed for the immobilization
遵循模块化方法来合成一系列富勒烯-离子-液体(IL)杂化物,其中IL部分(两个或十二个),阴离子和阳离子的数量已发生变化。C 60和IL的结合在结合物中产生新的独特性能,例如在水中的溶解度,在某些情况下,其溶解度高于800 mg mL -1。此外,C 60之一–IL杂化剂已用于通过离子交换固定硼纳米颗粒,然后再用硼氢化钠还原的方法固定钯纳米颗粒。出人意料的是,在还原过程中,形成了几个碳纳米结构,其中包括具有少量石墨烯侧壁的纳米洋葱和纳米笼,这些碳纳米结构已通过热重分析(TGA),X射线光电子能谱(XPS),X射线衍射进行了表征。 (XRD),扫描电子显微镜/能量色散X射线分析(SEM-EDAX)和高分辨率透射电子显微镜(HRTEM)。最后,如此获得的材料以0.2 mol%的浓度成功地用作了Suzuki和Mizoroki-Heck反应的催化剂。在以前的过程中,它可以循环使用五次,而不会损失活性。
