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 and imparts chirality to the core chromophore, resulting in circularly polarized luminescence signals ( = 0.8 × 10) with a quantum yield of 33% in the crystalline state. This novel set of compounds also showcases intriguing thermally reversible piezochromism.
我们展示了一类基于四芳基氨基硼烷（TAAB）的新型蓝色圆偏振发光体，其在固态下具有相当大的不对称因子。[具体化合物]中的手性侧基1-苯乙胺赋予核心发色团手性，在结晶状态下产生量子产率为33%的圆偏振发光信号（ = 0.8 × 10）。这组新型化合物还展现出有趣的热可逆压致变色现象。
