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.

有机硼烷基材料在催化、光电器件（例如非线性光学、有机发光二极管（OLED）、有机晶体管、有机光伏、智能窗等）、生物成像/探针和传感系统中具有重要而广泛的应用。有机硼烷化学和有机硼烷基材料的发展一直是我们研究的持续核心主题。我们的目标是发现和开发有机硼烷化合物的新光化学和反应活性，以便开发出更好的功能材料。 我们的研究将集中在以下主题：I.有机硼烷的光反应性，II。通过电子供体（膦或富电子金属中心）和电子受体（硼烷）的协同作用进行反应，III。用羧基修饰有机硼烷用于传感应用，以及 IV。用有机硼烷装饰金属化合物，用于 OLED。主题 I 将使我们获得有关有机硼烷光反应性的新知识和见解，并开发一类用于光电器件应用的新型 B-N 取代共轭材料。主题 II 将使我们能够建立新的方法来触发化学反应，用于化学转化和催化应用。主题 III 将使我们能够使用氟离子纸张开发有效的视觉传感系统，这对人类健康和环境很重要。主题 IV 将使我们能够开发用于 OLED 的高效蓝色荧光粉，这是一种非常具有挑战性的材料，在 OLED 行业中需求量很大，并将用于节能的下一代显示和照明设备。 所申请的资金将用于支持王小组每年8名研究生、两名暑期学生和四年级研究论文学生的研究活动。
