Although many chiral molecules exhibiting circularly polarized luminescence (CPL) have been reported recently, few molecular design guidelines are known for increasing the dissymmetry factor for CPL (g_lum). We demonstrate that a figure-eight-shaped molecule with D₂ symmetry has excellent chiroptical properties (Φ_f = 0.08, |g_lum| = 1.5 × 10^–2), which are attributed to the parallel arrangement of μ and m as well as a good |μ|/|m| ratio.

从分子轨道设计的圆偏振发光：具有D ₂对称性的八字形[5] ic烯二聚体

尽管最近已报道了许多表现出圆极化发光（CPL）的手性分子，但鲜为人知的分子设计指南可增加CPL（g _lum）的不对称因子。我们证明，用一个八字形形分子d ₂对称性具有良好的手性光学性质（Φ _˚F = 0.08，|克_LUM | = 1.5×10 ^-2），这归因于的平行布置μ和米以及好 μ | / | 米| 比。
