CAREER: Synthesis of Covalent Organic Frameworks with Novel Optoelectronic Properties

在这个由化学部大分子、超分子和纳米化学项目资助的项目中，康奈尔大学的William Dichtel将研究共价有机框架（COFs），这种框架由于其长程顺序而表现出有效的电荷传输。尽管COFs具有巨大的前景，但有限的COFs合成仍然是增加其复杂性的重大障碍。研究目标包括开发COF形成的新方法，制备长期以来被认为是有机光伏性能理想的COF基材料，以及研究其电荷分离和输运特性。该项目将几项教育举措与这些研究工作结合起来，包括为中学生举办太阳能科学研讨会，为高中科学教师提供专业支持，以及开发吸引人的内容，以提高公众对有机化学的认识。这项工作为提高有机电子器件的性能提供了一种新的策略，其经济重要性预计将在未来十年显著增长。COFs的新合成方法将使这些令人兴奋的材料得到许多其他应用。该项目还将有助于更深入地了解有机材料中的电荷分离和传输，这是提高有机光伏设备效率的关键过程。新的光伏技术对可持续能源生产和美国经济的未来至关重要。

In this project funded by the Macromolecular, Supramolecular and Nanochemistry Program of the Chemistry Division, William Dichtel of Cornell University will study covalent organic frameworks (COFs) that exhibit efficient charge transport as a consequence of their long-range order. Despite their great promise, the limited syntheses of COFs have remained a significant roadblock to increasing their complexity. The research objectives include developing new methods for COF formation, preparing COF-based materials with morphologies long thought to be ideal for organic photovoltaic performance, and studying their charge separation and transport properties. The project integrates several educational initiatives with these research efforts, including science workshops on solar energy for middle school students, professional support for high school science teachers, and developing engaging content that will enhance public awareness of organic chemistry.This work offers a new strategy for improving the performance of organic electronic devices, whose economic importance is expected to grow significantly over the next decade. New synthetic methods for COFs will enable and inspire many other applications for these exciting materials. The project will also contribute to a deeper understanding of charge separation and transport in organic materials, key processes for increasing the efficiency of organic photovoltaic devices. New photovoltaic technologies are critical to sustainable energy generation and the future of the United States economy.
