Fabrication of chiral photonic organic materials and structures

手征光子学与材料的手征对称性有关。它涉及手光学材料的制造，器件实现和基本理解。我们的研究目标是利用非手性分子制备新型手性有机材料，研究手性的生长和传播，研究其手性光学性质。第一部分是手性表面的制备、手性光学性质的研究以及作为模板用于手性材料的自组装。第二部分是利用二次谐波产生技术研究手性结构的形成和传播。二次谐波产生技术是一种表面特异性非线性光学诊断工具，其偏振特性携带手性特异性特征。第三是使用非线性圆二色性研究手性结构的建立和传播，这是一种体积特异性效应。我们相信，我们为具有许多预期应用的新材料提供了新的思路：-在生物和医学诊断中使用手性材料中的光传播来检测少量生物材料。- 自组织手性材料作为种子用于手性合成和药物应用中对映体的富集和分离。- 塑料光子学用大尺寸手旋非线性材料的发展。- 塑料电子新材料的开发。该研究计划将探索在物理和化学之间的边界与有机材料的光物质手性相互作用的几个方面，并将在皇后大学化学和物理系进行。

Chiral photonics is related to the chiral symmetry of materials. It involves the fabrication, device implementation and fundamental understanding of chiroptical materials. Our research objectives are to fabricate new chiral organic materials using achiral molecules, to study chirality growth and propagation, to investigate their chiroptical properties. First part is the fabrication of chiral surfaces, study of their chiroptical properties and use as templates for the self-assembly of chiral materials. Second part is study of the build-up and propagation of chiral structures using second-harmonic generation which is a surface-specific nonlinear optical diagnostic tool and whose polarization properties carry chiral-specific signatures. Third is study of the build-up and propagation of chiral structures using nonlinear circular dichroism which is a volume-specific effect. We believe that we shed a new light on new materials with many anticipated applications: - The use of light propagation in chiral materials to detect small amounts of biological materials in biological and medical diagnostics. - The use of self organized chiral materials as seeds for enantiomer enrichment and separation in chiral synthesis and pharmaceutical applications. - The development of large chiroptical-nonlinear materials for plastic photonics. - The development of new materials for plastic electronics. The research program will explore several aspects of light-matter chiral interaction with organic materials at the border between physics and chemistry and will be carried out in the Departments of Chemistry and Physics at Queen's University.
