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.
