摘要：

We present a new class of blue circularly polarized luminescentemitters based on tetraarylaminoborane (TAAB) with considerable dissymmetryfactor in the solid state. The chiral pendant 1-phenylethylamine in BN-RR and BN-SS imparts chirality to the core chromophore, resulting in circularlypolarized luminescence signals (g (lum) =0.8 x 10(-3)) with a quantum yield of 33% inthe crystalline state. This novel set of compounds also showcasesintriguing thermally reversible piezochromism.
