Fabrication of chiral photonic organic materials and structures

手征光子学与材料的手征对称性有关。它涉及手性材料的制造、装置实施和基本理解。我们的研究目标是利用非手性分子制备新的手性有机材料，研究手性的生长和传播，研究它们的手性性质。第一部分是手性表面的制备、手性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研究手性结构的建立和传播，二次谐波是一种表面特有的非线性光学诊断工具，其偏振特性带有手性特有的特征。第三，利用体积比效应的非线性圆二向色性研究了手性结构的建立和传播。我们相信，我们为新材料带来了新的曙光，具有许多预期的应用：-利用手性材料中的光传播来检测生物和医学诊断中的少量生物材料。-在手性合成和药物应用中使用自组织手性材料作为对映体浓缩和分离的种子。-开发用于塑料光子学的大型手写非线性材料。-开发塑料电子新材料。该研究计划将在物理和化学的交界处探索轻物质与有机材料手性相互作用的几个方面，并将在皇后大学的化学和物理系进行。

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.
