Organoborane-based materials have important and broad applications in catalysis, optoelectronic devices (e.g. non-linear optics, organic light emitting diodes (OLEDs), organic transistors, organic photovoltaic, smart windows etc), bio-imaging/probes and sensory systems. The development of organoborane chemistry and organoborane-based materials has been an on-going and central theme of our research. We aim to discover and exploit new photochemistry and reactivity of organoborane compounds so that better functional materials can be developed. Our research will focus on the following topics: I. Photoreactivity of organoboranes, II. Reactivity via cooperativity of electron donors (phosphine or electron-rich metal centers) and electron acceptors (boranes), III. Decorating organoboranes with carboxylic groups for sensing applications, and IV. Decorating metal compounds with organoboranes for use in OLEDs. Topic I will allow us to acquire new knowledge and insights on photoreactivity of organoboranes and to develop a new class of B-N substituted conjugated materials for applications in optoelectronic devices. Topic II will allow us to establish new methods to trigger chemical reactivity for applications in chemical transformation and catalysis. Topic III will enable us to develop effective visual sensing systems using papers for fluoride ions that are important for human health and the environment. Topic IV will allow us to develop highly efficient blue phosphors for OLEDs, a very challenging class of materials that are in high demand in OLEDs industry and will be used in energy efficient next generation display and lighting devices. The requested funding will support the research activity of 8 graduate students, two summer students and the 4th year research thesis students in the Wang group each year.

基于有机体的材料在催化，光电设备（例如非线性光学，有机光发射二极管（OLEDS），有机晶体管，有机光伏，智能窗口等），生物成像/探针和感觉系统中具有重要的广泛应用。有机化学化学和有机烷基材料的发展一直是我们研究的持续和中心主题。我们旨在发现和利用有机烷化合物的新光化学和反应性，以便可以开发出更好的功能材料。 我们的研究将重点介绍以下主题：I。有组织的光电反应性，ii。通过电子供体（磷酸或富含电子的金属中心）和电子受体（Boranes）合作的反应性，III。用羧基的有机菜素进行装饰，用于感应应用，而IV。用有机鸟烷在OLED中使用的金属化合物。主题我将允许我们获取有关有机烷的光电反应性的新知识和见解，并开发新的B-N取代的共轭材料，以用于光电设备中的应用。主题II将使我们能够建立新的方法来触发化学反应性，以在化学转化和催化中应用。主题III将使我们能够使用对人类健康和环境很重要的氟化离子进行有效的视觉传感系统。主题IV将使我们能够为OLED开发高效的蓝色磷光剂，OLED是一种非常具有挑战性的材料，在OLEDS行业需求量很高，并将用于节能下一代展示和照明设备。 要求的资金将支持每年王小组的8位研究生，两名夏季学生和第四年研究论文学生的研究活动。
