手性共轭有机三芳基硼(Ar₃B)发光材料研究进展

The chiral π-conjugated materials typically exhibit excellent photophysical properties and stable chiral characteristics, which have a wide range of applications in the field of organic optoelectronic materials. Due to the unique electronic properties of triarylboron (Ar3B), incorporating this framework into chiral π-conjugated systems results in systems with superior chiroptical properties, forming chiral conjugated organic triarylboron materials, and has attracted widespread attention in both chemistry and materials science. This review first introduces the basic concepts in the field of chiral conjugated organic triarylboron materials. Then, the synthetic strategies, structural characteristics of chiral conjugated triarylboron materials based on the source of chirality, including axial chirality, helical chirality, planar chirality, and central chirality are discussed. It also delves into the latest advances in these materials absorption spectrum, emission spectrum, fluorescence quantum efficiency, and other chiroptical optoelectronic properties, which are crucial for the performance of chiral organic optoelectronic devices. Finally, the current challenges and future development trends of chiral conjugated organic triarylboron materials are discussed, and the potential application of this material is reasonably anticipated.
