项目摘要

The Chemical Synthesis Program of the Chemistry Division supports the project by Professor Frieder Jaekle. Professor Jaekle is a faculty member in the Department of Chemistry at the Newark Campus of Rutgers University. He is developing new conjugated materials called polycyclic aromatic hydrocarbons (PAHs) that contain boron-containing units. The presence of the boron enhances the potential for the PAHs to serve as materials in optical and electronic devices. To this end, PAHs have proven to be effective platforms for building organic electronics, imaging, sensors, molecular switches, etc. In these settings, their performance is improved when the materials are "doped" with either electron-rich donor or electron-poor acceptor atoms that enhance conductivity. While the doping of PAHs with nitrogen and sulfur (both donors) has been studied extensively, research into systems with other heteroatoms remains less developed. Boron is very interesting as its electron-poor (acceptor) character can result in new, desirable properties for opto-electric devices. Professor Jaekle and his students are well-positioned to make and study the boron doped PAHs in order to fully develop their potential. The project also contributes to the training of a diverse group of students in an interdisciplinary research environment at the interface of organic, inorganic and materials chemistry. Another goal is to bring together researchers from different backgrounds in pursuit of new conjugated hybrid materials through organization of symposia, international collaborations, and broad dissemination of new knowledge in this field.The specific aims of the research are to: (1) develop regioselective methods for the targeted functionalization of PAHs at their periphery via Lewis base-directed electrophilic C-H borylation; (2) develop new approaches to incorporate multiple tricoordinate boron centers into the framework of PAHs; (3) investigate the effect of boron doping/functionalization on the electronic structure, photophysical properties, and chemical reactivity. New synthetic tools are developed that provide access to unique functional pi-conjugated systems with tailored properties. Strategic placement of boranes at well-defined positions in the periphery or framework of PAHs is expected to dramatically alter their electronic structure. The preparation of the new pi-conjugated hybrids is anticipated to lead to new materials with desirable optical, electronic, stimuli-responsive and sensory properties. The research is complemented by efforts to involve students from underrepresented groups, to engage in international and interdisciplinary collaborations, and to provide a forum for scientific exchange for researchers in the field of organic-inorganic hybrid materials.

化学部的化学合成计划由弗里德·贾克尔（Frieder Jaekle）教授支持该项目。 Jaekle教授是罗格斯大学纽瓦克校园化学系的教职员工。他正在开发新的称为多环芳烃（PAHS）的共轭材料，该材料包含含硼的单元。硼的存在增强了PAH在光学和电子设备中充当材料的潜力。为此，PAHS已被证明是构建有机电子，成像，传感器，分子开关等的有效平台。在这些情况下，当用富含电子的供体或电子贫困受体原子“掺杂”材料时，它们的性能得到改善。虽然已经对PAH掺杂了氮和硫（两个捐赠者），但对其他杂原子的系统的研究仍然不那么发达。硼非常有趣，因为它的电子贫困（受体）特征可以为光电设备带来新的，理想的特性。 Jaekle教授和他的学生有很好的位置，可以制作和研究硼掺杂的PAH，以充分发挥其潜力。该项目还为有机，无机和材料化学界面的跨学科研究环境中的一群学生培训。另一个目标是将来自不同背景的研究人员汇集到通过组织，国际合作组织的组织，国际合作以及在该领域中对新知识的广泛传播。研究的具体目的是：（1）开发：（1）开发区域性选择方法，用于通过Lewis Base-Base-base-direpectect operophiel contectectional oppherational operphatientiations of pahs; （2）开发新的方法将多个三角体硼中心纳入PAH的框架；（3）研究硼掺杂/功能化对电子结构，光物理特性和化学反应性的影响。开发了新的合成工具，可提供具有量身定制属性的独特功能性PI偶联系统。在PAHS的外围或框架中，硼烷在明确定义的位置上的战略放置有望极大地改变其电子结构。新型PI偶联的杂种的制备预计会导致具有理想的光学，电子，刺激性反应和感觉特性的新材料。这项研究的补充是让参与代表性不足的团体，进行国际和跨学科合作的学生，并为有机无机混合材料领域的研究人员提供科学交流的论坛。
