结晶性胶束因具有形态可控性好、各向异性显著的特点而受到广泛关注和研究，但目前对其形貌调控主要通过结晶链段实现，而对壳层链段构象关注较少。因此本项目拟通过合成结晶/离子液晶型嵌段共聚物，利用壳层链段与不同分子间的超分子相互作用来调控结晶性胶束的形貌。首先考察链结构和结晶条件对结晶/离子液晶型嵌段共聚物胶束形态的影响；其次，研究不同性质的反离子、主客体相互作用对胶束形态的影响，阐明归一化接枝密度与胶束形态的关系；最后通过液晶和结晶驱动力的协同作用制备尺寸均一的嵌段共聚物单晶，并以该单晶为自组装基元，研究在结晶驱动下，“二次自组装”的条件与机理，以实现不同嵌段共聚物之间的可控自组装。本项目的实施将对调控结晶性胶束的形貌以及构建复杂组装体的嵌段共聚物胶束具有重要的理论和实际意义。

Crystalline micelles have been widely investigated due to their controllable morphologies and highly anisotropic features. Nevertheless, regulation mean of crystalline micelles is limited to the crystalline block, while the effort devoted to the conformation of corona segments has been scarce. In this project, to enrich the regulation means of crystalline micelles, crystalline/ionic liquid crystalline block copolymers with different chain structures and compositions will be synthesized. It is expected that the morphology of crystalline micelles will be regulated by supermolecular interaction, i.e., interaction between added molecules and corona segment. The effect of chain structures and crystallization condition on morphologies will be firstly investigated. Then the effect of different counterions and host-guest interaction on crystalline micelles will be studied to reveal the relationships between the reduced tethering density and morphology of crystalline micelles. Finally, uniform-sized single crystals of crystalline/ionic liquid crystalline block copolymers are promoted to form driven by the cooperation of liquid crystalline order and crystallization. Using the single crystals as the self-assembly units, the condition and mechanism of “secondary self-assembly” driven by crystallization will be explored, thus the tailored morphologies between different crystalline block copolymers can be realized. The study of the present project is expected to have an important contribution to regulation of morphologies of crystalline micelles and construction of block copolymer micelles with complex shape both in theory and practice.
