近年来，手性配体钝化的过氧化物材料显示出独特的手性光活性，具有良好的光电应用前景。然而，配体仅限于手性胺。在这里，手性磷酸分子已被用于合成CsPbBr 3纳米片。纳米片显示出明显的圆二色谱信号，并保持其手性与反溶剂纯化后的性质。
Perovskite materials passivated by chiral ligands have recently shown unique chiroptical activity with promising optoelectronic applications. However, the ligands have been limited to chiral amines. Here, chiral phosphate molecules have been exploited to synthesize CsPbBr3 nanoplatelets. The nanoplatelets showed a distinct circular dichroism signal and maintained their chiroptical properties after purification with anti-solvent.
