Chirality is ubiquitous in nature, and circularly polarized luminescence (CPL) is one of the key features of some chiral non-racemic luminescent systems. Among the developed CPL-active systems, chiral metal–organic materials (MOMs) have become tremendously meaningful due to the combination of coordination-bonded metal centers and organic ligands. This brings specific opportunities in the design of novel structures including coordination polymers, discrete supramolecular assemblies, and other types of coordination complexes with molecular or supramolecular-leveled chirality, which can be originated from ligand or metal-based chirogens and luminogens. In these chiral MOMs, CPL properties might be aroused or amplified under suitable arrangement of chirogens and luminogens, for which, effective strategies like controlled self-assembly for helicity amplification, aggregation of luminogens, charge transfer, energy transfer, etc, have been put forward. As a result, exciting potential applications have been found in such fields as CPL-OLED, stereo-biochemistry and biomedicine, chiral recognition and sensing, chiroptical photoswitches, security devices and so on. In this review, we will mainly discuss the recent progress made in CPL MOMs, including the basic concepts, major parameters and characterization methods, mechanism and designing origins, different structural categories, effective strategies to enhance CPL performance, as well as their practical applications and prospects.

手性在自然界中无处不在，圆偏振发光（CPL）是一些手性非外消旋发光系统的关键特征之一。在已开发的 CPL 活性体系中，手性金属有机材料（MOM）由于配位键金属中心和有机配体的结合而变得非常有意义。这为新型结构的设计带来了特殊的机会，包括配位聚合物、离散的超分子组装体以及其他类型的具有分子或超分子水平手性的配位配合物，这些配位化合物可以来源于配体或金属基的致冷剂和发光剂。在这些手性 MOM 中，CPL 特性可能会在适当排列的chirogens 和luminogens 下被激发或放大，为此，提出了控制自组装螺旋放大、发光团聚、电荷转移、能量转移等有效策略。因此，在 CPL-OLED、立体生物化学和生物医学、手性识别和传感、手性光开关、安全设备等领域发现了令人兴奋的潜在应用。在这篇综述中，我们将主要讨论 CPL MOMs 的最新进展，包括基本概念、主要参数和表征方法、机理和设计起源、不同的结构类别、提高 CPL 性能的有效策略，以及它们的实际应用和前景。在 CPL-OLED、立体生物化学和生物医学、手性识别和传感、手性光开关、安全设备等领域发现了令人兴奋的潜在应用。在这篇综述中，我们将主要讨论 CPL MOMs 的最新进展，包括基本概念、主要参数和表征方法、机理和设计起源、不同的结构类别、提高 CPL 性能的有效策略，以及它们的实际应用和前景。在 CPL-OLED、立体生物化学和生物医学、手性识别和传感、手性光开关、安全设备等领域发现了令人兴奋的潜在应用。在这篇综述中，我们将主要讨论 CPL MOMs 的最新进展，包括基本概念、主要参数和表征方法、机理和设计起源、不同的结构类别、提高 CPL 性能的有效策略，以及它们的实际应用和前景。
