CAREER: Synthesis of Covalent Organic Frameworks with Novel Optoelectronic Properties

在这项由化学系大分子、超分子和纳米化学计划资助的项目中，康奈尔大学的威廉·迪希特尔将研究由于其长程有序而表现出高效电荷传输的共价有机骨架(COF)。尽管COF的合成前景看好，但其有限的合成仍然是增加其复杂性的重要障碍。研究目标包括开发形成COF的新方法，制备具有长期以来被认为是理想的有机光伏性能的COF基材料，并研究其电荷分离和传输特性。该项目将几项教育举措与这些研究工作结合在一起，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，以及开发将提高公众对有机化学的认识的引人入胜的内容。这项工作为提高有机电子设备的性能提供了一种新的战略，其经济重要性预计在未来十年将显著增长。用于COF的新的合成方法将使这些令人兴奋的材料的许多其他应用成为可能。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，这是提高有机光伏器件效率的关键工艺。新的光伏技术对可持续能源发电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.
