项目摘要

In this project funded by the Chemical Synthesis Program of the NSF Chemistry Division, Professor Frieder Jaekle develops new conjugated hybrid materials that contain electron-deficient Group 13 elements (boron, aluminum, gallium, and indium). Conjugated organic materials enjoy ubiquitous applications in organic electronics, sensory materials, and supramolecular chemistry. This research aims to take advantage of recent advances in the field of Main Group Chemistry for the development of new types of conjugated hybrid materials. Organoborane groups offer electron-acceptor effect that are useful in new solution-processible materials for light emitting devices (LEDs), field-effect transistors (FETs), and photovoltaics (OPVs) - applications where acceptor materials remain in high demand. In addition, Lewis acidic organoboranes show promise as sensors for anions and other toxic small molecules. Selective boron-silicon and boron-tin exchange chemistries, Lewis base-directed electrophilic aromatic substitutions, and strategies for borenium cation formation are exploited to prepare new classes of pi-conjugated materials that are expected to exhibit: (i) strong electron-acceptor character, (ii) charge transfer and two-photon absorption properties, and (iii) a propensity for assembly on surfaces or interaction with other carbon nanomaterials. The project contributes to the training of a diverse group of students in an interdisciplinary research environment. A special focus is placed on the training of students from groups underrepresented in chemistry (e.g. American Chemical Society Project SEED high school students). Students benefit from collaborations with physical chemists in the US and Germany. In addition, Professor Jaekle organizes symposia and conferences such as the annual "Boron in the Americas" meeting.

在由NSF化学部化学合成计划资助的该项目中，Frieder Jaekle教授开发了包含电子缺陷型组13个元素（Boron，Aluminum，Gallium和Indium）的新的共轭混合材料。共轭有机材料在有机电子，感觉材料和超分子化学中享有无处不在的应用。这项研究旨在利用主要小组化学领域的最新进展，以开发新型的共轭混合材料。有机体组提供的电子感受器效应可用于新的溶液可加工材料，用于发光设备（LED），现场效应晶体管（FET）和光伏电动机（OPV） - 受体材料保持高需求的应用。此外，刘易斯酸性有机烷虫作为阴离子和其他有毒小分子的传感器显示出希望。利用选择性的硼 - 丝硅和硼键交换化学，刘易斯基底导向的电芳族芳族取代和硼阳离子形成的策略来准备新的PI偶联材料，这些材料有望展示：（i）强大的电子受体特征（ii）电荷转移和两光子吸收特性，以及（iii）在表面上组装或与其他碳纳米材料相互作用的倾向。该项目为在跨学科研究环境中培训一群学生。特别重点放在对化学成分不足的小组的培训（例如，美国化学学会计划种子高中生）。学生从与美国和德国的物理化学家的合作中受益。此外，Jaekle教授组织了研讨会和会议，例如年度“美洲硼”会议。
