三个二嵌段共聚物，每一个由一个相对极性的聚氧乙烯酸酯嵌段和一个非极性的聚噻吩嵌段组成，研究了它们的溶液自组装行为。已观察到中空球形泡状结构;它们的形成是由疏溶剂-亲溶剂相互作用驱动的。囊泡的大小可以通过改变溶剂的极性来控制。当溶剂组合相对极性时似乎形成规则囊泡，而当溶剂相对非极性时形成反向囊泡。
Three diblock copolymers, each consisting of a relatively polar polyoxometalate-containing block and a nonpolar polythiophene block, were studied for their solution self-assembly behavior. Hollow spherical vesicular structures have been observed; their formation is driven by solvophobic–solvophilic interactions. The size of the vesicles can be controlled by varying the polarity of the solvent. Regular vesicles seem to form when the solvent combination is relatively polar, while reverse vesicles form when the solvent is relatively nonpolar.
