Metal-organic frameworks (MOFs) have recently emerged as a new type of prospective photocatalytic material due to their characteristics such as tunable structures, pore modification, crystalline nature with eliminated structural defects, unique semiconductor properties, etc. However, most of these systems also suffer from low activity, high cost, and low visible light utilization. Xanthene dyes are eco-friendly organic dyes used in photocatalysis. They possess the advantages of low cost, low toxicity, and high visible light response; so, they can be directly used as building blocks to fabricate MOF materials or as proper cocatalysts to increase the absorbance of irradiation leading to the construction of a reasonable photocatalytic system. Herein, we have summarized the recent developments in the study of MOFs containing xanthene dyes for photocatalytic applications. The paper can be divided into two sections depending on whether the xanthene dyes are coordinated in the MOF structure: (i) MOFs synergized with xanthene dyes for photocatalytic applications and (ii) MOFs with xanthene dyes incorporated within ligand backbones for photocatalytic applications. Moreover, in this paper, the present challenges and future opportunities in this field are also discussed.
金属有机框架（MOF）近年来作为一种新型的潜在光催化材料而出现，这归因于其诸如可调节结构、孔修饰、具有消除结构缺陷的晶体性质、独特的半导体性质等特征。然而，这些体系中的大多数也存在活性低、成本高和可见光利用率低的问题。呫吨染料是用于光催化的环保型有机染料。它们具有成本低、毒性低和可见光响应高的优点；因此，它们既可以直接用作构建MOF材料的基本单元，也可以作为合适的助催化剂来提高辐照吸收率，从而构建合理的光催化体系。在此，我们总结了含呫吨染料的MOF用于光催化应用研究的最新进展。根据呫吨染料是否在MOF结构中配位，本文可分为两个部分：（i）与呫吨染料协同用于光催化应用的MOF，以及（ii）在配体主链中掺入呫吨染料用于光催化应用的MOF。此外，本文还讨论了该领域当前面临的挑战和未来的机遇。
