We present a new class of blue circularly polarized luminescent emitters based on tetraarylaminoborane (TAAB) with considerable dissymmetry factor in the solid state. The chiral pendant 1-phenylethylamine in BN-RR and BN-SS imparts chirality to the core chromophore, resulting in circularly polarized luminescence signals (glum = 0.8 � 10-3) with a quantum yield of 33 in the crystalline state. This novel set of compounds also showcases intriguing thermally reversible piezochromism. © 2023 American Chemical Society.
