Stable High-Spin Polyradicals and Chiral pi-Conjugated Systems

有了这个更新奖，化学结构、动力学和机制项目将继续支持内布拉斯加州大学的Andrzej Rajca教授的一个项目，该项目涉及稳定的多自由基和手性共轭体系的合成和表征。所研究的多自由基将是高自旋稳定的有机分子，具有强的全键铁磁偶联，并有可能作为具有大磁矩和磁有序的有机聚合物的基石。要合成的手性共轭分子将从螺旋结构中推导出它们的不对称性，并旨在提供对控制新型手性分子合理设计的原理的理解。这些研究将有助于理解有机分子和大分子的结构和性质关系，这些关系与新型磁性和光学材料的发展有关。这个跨学科的研究项目，涉及多步骤有机合成，有机分子的各种物理特性，分子磁学物理和计算化学，将为学生提供各种现代研究技术的广泛训练。

With this Renewal Award, the Chemical Structure, Dynamics, and Mechanisms Program continues to support Professor Andrzej Rajca of University of Nebraska in a project involving the synthesis and characterization of stable polyradicals and chiral conjugated systems. The polyradicals to be studied will be high-spin stable organic molecules with strong through-bond ferromagnetic coupling and the potential to serve as building blocks for organic polymers with large magnetic moments and magnetic order. The chiral conjugated molecules to be synthesized will derive their asymmetry from helical structures and are designed to provide an understanding of the principles governing the rational design of novel chiral molecules. These investigations will contribute to an understanding of the structure and property relationships in organic molecules and macromolecules that are relevant to the development of novel magnetic and optical materials. This interdisciplinary research project, involving multi-step organic synthesis, diverse physical characterization of organic molecules, the physics of molecular magnetism, and computational chemistry, will provide students with broad training in a variety of modern research techniques.
