Circularly polarized luminescence, or CPL, is a luminescence phenomenon that provides the differential emission intensity of right and left circularly polarized light, thereby providing information on the excited state properties of the chiral molecular systems. In recent years, there has been a growing interest toward the development of organic chromophores capable of circularly polarized emission due to their potential applications in sensors, asymmetric synthesis as well as display and optical storage devices. The major drawback with organic molecules is the low dissymmetric factors exhibited by these systems. One of the recent strategies adopted for the improvement in luminescence dissymmetry of organic systems is through the controlled self-assembly of chromophores. In this Perspective, we highlight the recent experimental and theoretical developments in the field of chiral organic chromophoric systems and their self-assembly, that has produced promising results toward the enhancement of g_lum values in CPL.

手性分子和超分子组装中的圆偏振发光

圆偏振发光或CPL是一种发光现象，可提供左右圆偏振光的差分发射强度，从而提供有关手性分子系统的激发态性质的信息。近年来，由于其在传感器，非对称合成以及显示和光学存储设备中的潜在应用，人们对开发能够圆极化发射的有机发色团的兴趣日益浓厚。有机分子的主要缺点是这些系统表现出的低不对称因子。用于改善有机系统的发光不对称性的最新策略之一是通过发色团的受控自组装。从这个角度来看，CPL中的g _lum值。
