[K(dibenzo-18-crown-6)]+ (KC) cations are used for cocrystallization with manganese halides, producing isostructural single crystals of organic-inorganic hybrid complexes, [K(dibenzo-18-crown-6)]2MnX4 (abbreviated (KC)2MnX4) (X=Cl, Br), which feature one-dimensional (1D) morphology and green phosphorescence with considerable photoluminescence quantum yields (PLQYs) accompanied by excellent optical waveguide behavior with a low loss coefficient. More interestingly, (KC)2MnX4 crystallizes in the monoclinic space group Cc belonging to the achiral point group m (Cs), where the noncentrosymmetric arrangement of racemic units, with right- and left-handed rotating optical axes, endows these achiral single crystals with circularly polarized luminescence (CPL), observed for the first time.

杂化卤化锰非手性单晶的圆偏振发光

[K(dibenzo-18-crown-6)]+ (KC) 阳离子用于与卤化锰共结晶，产生有机-无机杂化复合物的同构单晶，[K(dibenzo-18-crown-6)]2MnX4 (缩写为 (KC)2MnX4) (X=Cl, Br)，具有一维 (1D) 形态和绿色磷光，具有可观的光致发光量子产率 (PLQY)，同时具有出色的光波导行为和低损耗系数。更有趣的是，(KC)2MnX4 在属于非手性点群 m (Cs) 的单斜空间群 Cc 中结晶，其中外消旋单元的非中心对称排列，具有左右手旋转光轴，赋予这些非手性单晶圆偏振发光（CPL），首次观察到。
