一种疏水化合物，我们命名为3c18 -偶氮，它含有一个偶氮头和三个18c烷基链，通过包合作用在其上盖上环糊精（CD），可以形成两亲性化合物。两亲性化合物在水中自组装成囊泡。通过可见光和紫外交替照射实现组装和拆卸的光开关，使偶氮基团异构化，从而影响其与CDs的络合。
A hydrophobic compound, which we name 3C18-Azo, containing an azo head and three 18 C alkyl chains has the capacity to form an amphiphile by capping it with a cyclodextrin (CD) by inclusion complexation. The amphiphilic compound self-assembles into vesicles in water. Optical switching of the assembly and disassembly is realized by alternating visible and UV irradiation, which causes the isomerization of the azo groups, thus affecting their complexation with the CDs.
