摘要

通过连续的乌基反应，分两个步骤获得了笼状微结构。在第一阶段，在水悬浮液中获得了具有畴结构的基于羧甲基纤维素和壳聚糖的亚微米胶体颗粒。第二阶段，在皮克林乳液表面用甲苯进行乌基反应。除去甲苯并在水中重新溶解后，得到了表面带有大孔的胶体。在 Ugi 反应过程中改变交联密度可以获得不同孔径的结构。

Cage-like microstructures via sequential Ugi reactions in aqueous emulsions.

Cage-like microstructures were obtained in two steps by sequential Ugi reactions. At the first stage, submicron colloidal particles based on carboxymethylcellulose and chitosan with a domain structure were obtained in an aqueous suspension. In the second stage, the Ugi reaction was carried out on the surface of the Pickering emulsions with toluene. Removal of toluene and redissolution in water resulted in colloidosomes with large holes on the surface. Varying the cross-link density during the Ugi reaction made it possible to obtain structures with different hole sizes.
