Photoresponsive organoboron compounds have important and broad applications in optoelectronic and energy conversion 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 use light as the stimulus to energize molecules so that they can perform useful tasks or undergo rare structural transformation/bond activation that is not possible or difficult to achieve in the ground state. We aim to understand, discover and exploit new photochemistry and reactivity of organoborane compounds in order to advance boron chemistry and achieve better functional materials. Our research will focus on the following projects: I. Asymmetric Photochromic Boron Compounds, II. Breaking Unstrained C-C bonds in Arenes via Photoisomerization, III. Photoisomerization vs Photoelimination of Asymmetric Boron Systems, and IV. Hybrid BN-Embedded Conjugated Materials. Project I will allow us to acquire new knowledge and insights on photoreactivity of organoboranes and develop innovative approaches in breaking chemical bonds. Project II will allow us to establish a new light-facilitated protocol of breaking and transforming highly stable C-C bonds in molecules such as benzene under mild conditions without the use of transition metal activators or reducing reagents. Project III will enable us to control phototransformation of organoboron compounds and develop new and unconventional strategies in creating new photochromic materials and new BN-doped conjugated materials for optoelectronic devices. Project IV will allow us to develop highly efficient and stable blue phosphors and charge transport materials for orangic light emitting diodes and organic field effect transistors, a very challenging class of materials that will be used in the next generation of energy conversion devices. The requested funding will support the research activity of 7 M.Sc, 9 Ph.D. students, 10 summer undergraduate students and 10 4th year honours research thesis students in my group at Queen's University and a number of visiting graduate students from Japan, Germany and China for a period of 5 years.

光呼吸有机元化合物在光电和能量转换设备中具有重要的和广泛的应用（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），生物对象/探测/探测/探测/探针和感官系统。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。 我们使用光作为刺激来启用分子，以便它们可以执行有用的任务或经历罕见的结构转化/键激活，而在基态下无法实现或难以实现。我们的目标是了解，发现和利用有机烷化合物的新光化学和反应性，以推动硼化学并实现更好的功能材料。 我们的研究将重点放在以下项目上：I。非对称光致变色硼化合物，ii。通过光异构化在竞技场中打破未训练的C-C键，iii。光异构化与非对称硼系统的光启示性和IV。混合BN包裹的共轭材料。项目我将允许我们获得有关有机菜烷的光反应性的新知识和见解，并开发出破坏化学债券的创新方法。项目II将允许我们建立一种新的光辅助方案，即在轻度条件下，不使用过渡金属激活剂或还原试剂，以破坏和转化分子（例如苯）中的高度稳定的C-C键。 III项目将使我们能够控制有机体化合物的光转换，并制定新的和非常规的策略，以创建新的光更色块材料和新的BN掺杂的偶有的共轭材料，以用于光电设备。 IV项目将使我们能够开发出高效且稳定的蓝色磷光器，并为橙色发光二极管和有机田间效应晶体管充电传输材料，这是一种非常具有挑战性的材料类，将用于下一代能量转换设备。 要求的资金将支持7 M.Sc的研究活动，9博士学位。学生，10名夏季的本科生和10个4年荣誉奖学金，在皇后大学的小组中，以及来自日本，德国和中国的许多来访的研究生5年。
