    Abstract: 以往人們都是以得到的物質之性質來選擇適合它的用途,然而我們都知道世界上所有物質都是以分子或是原子組裝而成;所以理論上,我們可以調整自組裝結構來設計出我們想要的物理性質的物質,也就是說,以往是使用由上而下的方式,而此篇研究想以由下而上的方式來設計我們想要的物質。
    透過此研究,我們得知能從自發曲率及彎曲模數觀察自組裝行為,所以只要知道其參數便能設計我們想要的物質。;Materials are assembled molecule by molecule, theoretically, as long as understanding of their structures, assembly properties of individual molecular, this is likely to use ‘bottom-up’ approach to design the materials which we want by changing their structures.
    In order to design materials, finding out how self-assembly behavior is affected by the chemical structure of the substance, external environmental factors and external forces, and coming to understand the relationship between them.
    The relation between molecular structure and self-assembly properties can describe by packing parameter, but it exists some disadvantage, on the contrary, at continuum mechanics, the monolayer formed self-assembly behavior is considered a continuous flexible solid thin film, and it can describe by the elastic energy density.
    Through our experiment (SAXS and SANS), We think that we could use the spontaneous curvature and bending modulus to check the self-assembly structure, so when we know these parameters, we could develop the structure we wanted.
