Metal–organic complexes assembled from coordinative interactions are known to be able to display a wide range of photoluminescent behaviors benefiting from an extensive number of metal ions, organic linkers, and inclusion guests, depending on the multifaceted nature of their chemical structures and photophysical properties. In the past two decades, the white-light-emitting (WLE) and photoluminescent color-tuning (PLCT) materials based on the single-phase metal–organic coordination assemblies have merited particular attention and gained substantial advances. In this review, we give an overview of recent progress in this field, placing emphasis on the WLE and PLCT properties realized in the single-phase materials, which covers the origin, generation, and manipulation of different types of photoluminescence (PL) derived from ligand-centered (LC), metal/cluster-centered (MC or CC), excimer/exciplex-based (EX), metal-to-ligand or ligand-to-metal charge-transfer-based (MLCT or LMCT), or guest-included emissions. The coordination assemblies in this topic can be generally classified into three categories [(1) mono/homometallic coordination assemblies based on main group (s,p-block), transition (d-block), or lanthanide (f-block) metal centers, (2) s/p–f-, d–f-, or f–f-type heterometallic coordination assemblies, and (3) guest-included coordination assemblies] for which WLE and PLCT properties can be achieved by virtue of either a wide-band/overlapped emission covering the whole visible spectrum from a single emitting center or a combination of complementary color emissions from multiple emitting centers/origins. Some state-of-the-art assembly methods and successful design models relevant to the above three categories are elaborated to demonstrate how to achieve efficient and controllable white-light emission in a single-phase material through a tunable PL approach. Potential applications in the fields of lighting and displaying, sensing and detecting, and barcoding and patterning are surveyed, and at the end, possible prospects and challenges for future development along this line are proposed.

单相发白光致发光配色组件

已知通过配位相互作用组装的金属有机配合物能够显示出广泛的光致发光行为，这取决于它们的化学结构和光物理性质的多方面性质，这得益于大量的金属离子，有机连接基和夹杂物。在过去的二十年中，基于单相金属-有机配位组件的白光发射（WLE）和光致发光彩色调谐（PLCT）材料受到了特别的关注，并取得了长足的进步。在这篇综述中，我们概述了该领域的最新进展，重点放在单相材料中实现的WLE和PLCT特性上，这些特性涵盖了源自，衍生和产生的不同类型的光致发光（PL）的来源。以配体为中心（LC），金属/簇中心（MC或CC），基于准分子/激基复合物（EX），金属到配体或配体到金属的电荷转移（MLCT或LMCT）或客体包含的发射。本主题中的协调组件通常可以分为三类[（1）基于主要组（s，p块），过渡（d块）或镧系元素（f块）的金属/单金属/协调金属组件，（2）s / p-f-，d-f-或f-f型异金属配位组件，以及（3）包含客体的配位组件]，可以通过以下方式获得WLE和PLCT属性：宽带/重叠发射，覆盖单个发射中心的整个可见光谱，或者多个发射中心/源的互补色发射的组合。详细阐述了与上述三类相关的一些最新组装方法和成功的设计模型，以演示如何通过可调PL方法在单相材料中实现有效且可控的白光发射。对照明和显示，传感和检测以及条形码和图案化领域中的潜在应用进行了调查，最后，提出了沿这条线发展的可能前景和挑战。
