Construction of conjugated structures containing organoboron complexes

有机硼聚合物作为构建先进光电子器件的关键材料受到了广泛关注。硼配合物与其他功能单元之间的电子相互作用和相关性是含有机硼聚合物的特征光学和电学性质的原因。为了进一步理解这些性质的起源和应用于下一代新材料，不仅收集了聚合物中每个有机硼络合物的电子状态和行为的基础知识，而且还收集了聚合物在器件中的功能和性能。本课题合成了一系列有机硼聚合物。例如，合成了含有酮亚胺或硼酮亚胺基的共轭聚合物，并研究了它们的光学性质。聚合物表现出共轭体系通过聚合物主链的扩展和聚集诱导的发射。

The organoboron-containing polymers have attracted much attention as a key material for constructing advanced optoelectronic devices. The electronic interaction and correlation between the boron complexes and other functional units are responsible for the characteristic optical and electric properties of the organoboron-containing polymers. For further understanding of the origins of these properties and applying for the next generation of new materials, not only the fundamental knowledge on the electronic states and behaviors of each organoboron complex in the polymers but also on the functions and performances of the polymers in the devices have been gathered. In this project, the series of organoboron-containing polymers were synthesized. For instance, conjugated polymers including ketoimine or boron ketoiminate units were synthesized and their optical properties were investigated. The polymers exhibited the expansion of conjugation systems through the polymer main-chains and aggregation induced emissions.
