Circularly polarized luminescent (CPL) materials are promising in applications such as 3D displays and quantum communication. Hybrid organic-inorganic copper(I) iodides have been rapidly developed due to their intense photoluminescence and structural diversity; nevertheless, the reported Cu-I clusters rarely show CPL activities. In this study, we introduced chiral organic molecules R/S-methylbenzylammonium (R/S-MBA) into Cu-I inorganic skeletons to achieve chiral tetranuclear (R/S-MBA)4Cu4I4 clusters with intense orange luminescence and CPL activity at room temperature. These enantiomeric (R/S-MBA)4Cu4I4 clusters show oppositely signed circular dichroism (CD) signals, which agree well with their simulated electronic CD spectra. The crystallization-induced helical arrangement of (R/S-MBA)4Cu4I4 clusters and their largely distorted polynuclear configuration demonstrate a new platform for the study of chiral-related properties.

手性四核碘化铜簇的圆偏振发光。

圆偏振发光（CPL）材料在诸如3D显示器和量子通信等应用中很有前途。杂化有机-无机碘化铜（I）由于其强烈的光致发光和结构多样性而得到迅速发展。但是，报告的Cu-I簇很少显示CPL活性。在这项研究中，我们将手性有机分子R / S-甲基苄基铵（R / S-MBA）引入Cu-I无机骨架中，以实现具有强烈橙色发光和CPL活性的手性四核（R / S-MBA）4Cu4I4团簇。。这些对映异构体（R / S-MBA）4Cu4I4簇显示相反符号的圆二色性（CD）信号，这与它们的模拟电子CD光谱非常吻合。
