项目摘要

I will be applying organic synthetic techniques to forming novel molecules which have either a helical or figure-ofeightshape. These molecules are chiral and offer intriguing possibilities for the manipulation of bulk phases in thecontext of mirror image symmetry breaking. We will especially look to study self-assembly and their use as dopantsin liquid crystalline materials. Some intriguing possibilities are to develop these materials with a view to examining thepossibility of whether we can form exotic soft-matter topological quasiparticles.We will seek to characterise these materials with a range if imaging techniques including polarised opticalmicroscopy, confocal microscopy, electron microscopy and high-speed dynamical imaging.We envisage the reproducible formation of topological defects in small dimension droplets as having remarkableoptical properties with possible future directions in display and memory storage applications. We will work closelywith soft-matter modellers and work towards an understanding of how such complex knotted defects form in adynamical context. The topological defects we have started to examine have implications of self-assembledstructures from the small to the large scales, i.e. particle physics through to cosmology, and hence manageablescales, such as soft-matter chemistry offer an ideal opportunity to expand our knowledge across scales in thephysical sciences.

我将应用有机合成技术来形成具有螺旋形或八字形的新型分子。这些分子是手性的，为在镜像对称性破缺的背景下操纵体相提供了有趣的可能性。我们将特别研究自组装及其作为液晶材料中的掺杂剂的用途。一些有趣的可能性是开发这些材料，以检验我们是否可以形成奇异的软物质拓扑准粒子的可能性。我们将寻求利用一系列成像技术来表征这些材料，包括偏光光学显微镜、共焦显微镜、电子显微镜和高分辨成像技术。 -速度动态成像。我们设想小尺寸液滴中拓扑缺陷的可重复形成具有显着的光学特性，在显示和内存存储应用中可能具有未来的发展方向。我们将与软物质建模者密切合作，努力了解这种复杂的打结缺陷是如何在动态环境中形成的。我们开始研究的拓扑缺陷对从小尺度到大尺度的自组装结构都有影响，即从粒子物理学到宇宙学，因此可管理的尺度，如软物质化学，为我们跨尺度扩展知识提供了理想的机会。物理科学。
