Planar Chiral B-N Heteroarenes Based on [2.2]Paracyclophane as Circularly Polarized Luminescence Emitters

Planar chiral boron-nitrogen heteroarenes based on [2.2]paracyclophane were successfully synthesized in a few steps as a new family of circularly polarized luminescence emitters. It represents the first case of boron-nitrogen heteroarenes with planar chirality. Those compounds have been demonstrated to exhibit strong circularly polarized luminescence signals and high quantum yields, in both solution and doped film (with g(lum) up to 5.0 x 10(-3) and Phi(solution) up to 73%).
