Chiral molecules on curved colloidal membranes

摘要:

胶体膜是由棒状分子自组装而成的单层膜,它为设计具有特定形状和曲率的膜提供了模板,并可能在未来提供新的功能。通常,由于其分子手性,组成杆相对于膜法线倾斜。弯曲膜上这种倾斜的空间模式是由耗尽力、双极性相互作用、分子手性和边界效应之间的竞争引起的。我们提出了一个协变理论的倾斜模式上最小的表面,像螺旋面和悬链面,这已经在实验室中产生的最近。我们预测了几个不均匀的倾斜模式,其中一些是一致的实验观察和一些,这是尚未被发现。

英文摘要:

Colloidal membranes, self assembled monolayers of aligned rod like molecules, offer a template for designing membranes with definite shapes and curvature, and possibly new functionalities in the future. Often the constituent rods, due to their molecular chirality, are tilted with respect to the membrane normal. Spatial patterns of this tilt on curved membranes result from a competition among depletion forces, nematic interaction, molecular chirality and boundary effects. We present a covariant theory for the tilt pattern on minimal surfaces, like helicoids and catenoids, which have been generated in the laboratory only recently. We predict several non-uniform tilt patterns, some of which are consistent with experimental observations and some, which are yet to be discovered.
