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.

光响应有机硼化合物在光电和能量转换器件（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。 我们使用光作为刺激来为分子提供能量，以便它们能够执行有用的任务或经历在基态下不可能或难以实现的罕见结构转变/键激活。我们的目标是了解、发现和开发有机硼烷化合物的新光化学和反应活性，以推进硼化学并获得更好的功能材料。******我们的研究将集中在以下项目：I.不对称光致变色硼化合物，II 。通过光异构化打破芳烃中的无张力 C-C 键，III。不对称硼系统的光异构化与光消除，以及 IV。杂化氮化硼嵌入共轭材料。项目 I 将使我们获得有关有机硼烷光反应性的新知识和见解，并开发打破化学键的创新方法。项目 II 将使我们能够建立一种新的光促进方案，在温和条件下断裂和转化苯等分子中高度稳定的 C-C 键，而无需使用过渡金属活化剂或还原剂。项目III将使我们能够控制有机硼化合物的光转化，并开发新的非常规策略来创造用于光电器件的新型光致变色材料和新型氮化硼掺杂共轭材料。项目 IV 将使我们能够开发高效、稳定的蓝色荧光粉和用于有机发光二极管和有机场效应晶体管的电荷传输材料，这是一种非常具有挑战性的材料，将用于下一代能量转换器件。 ******所申请的资金将支持 7 名硕士、9 名博士的研究活动。我组在女王大学有 10 名暑期本科生和 10 名四年级荣誉研究论文学生，以及一些来自日本、德国和中国的访问研究生，为期 5 年。
