Abstract
The development of small organic CPL-active molecules with large luminescent dissymmetry factors and high quantum yields is highly demanded due to their promising applications in chiroptical devices and sensors. In this paper, we report the synthesis and the chiral optical properties of a series of axial chiral triarylborane dyes. These dyes were facile synthesized by direct borylation of commercially available enantiopure binaphthalenes, and display intense CPL with moderate luminescent dissymmetry factors and high quantum yields in both solution and solid-state, which enable them as efficient CPL emitters. Moreover, fluoride-controlled fluorescence and CPL signals of these dyes were realized, demonstrating their potential application as CPL sensors.
