With less heat emission, longer lifetime, and high energy yield, light-emitting Diodes (LEDs) have been studied as a substitute for conventional light sources. Following various studies developing LED components based on semiconductors, organic materials, and polymers, LEDs based on a new class of materials called metal organic frameworks (MOFs) has been reported. Due to high tunability and multifunctionality of the novel organic-inorganic hybrid material, MOFs, white light-emitting diodes based on those materials, have the highest CRI and CIE coordinates nearest to (0.33, 0.33) (White light) among those reported. In this study, MOFs used for LED components are reviewed. It was found that MOFs are used for LED components in two main sectors, white phosphor and light emissive layer. MOFs used for light emissive layer exhibited electroluminescence by the presence of organic linkers, metals, and their interactions such as MLCT or LMCT. Several MOFs showed electroluminescence by guest molecules. The main hindrance for wide use of MOFs for LEDs are energy efficiency, lack of red light, and stabily. Studies to overcome those obstacles have been introduced. Based on those studies, we provide possible solutions for current challenges and various perspectives that MOF-based LEDs researcher should consider.

发光二极管 (LED) 具有更少的热辐射、更长的寿命和高能量产出，已被研究作为传统光源的替代品。在开发基于半导体、有机材料和聚合物的 LED 组件的各种研究之后，已经报道了基于称为金属有机框架 (MOF) 的新型材料的 LED。由于新型有机-无机杂化材料的高度可调性和多功能性，基于这些材料的 MOF 白光发光二极管具有最高的 CRI 和 CIE 坐标，最接近于 (0.33, 0.33)（白光）。在这项研究中，回顾了用于 LED 组件的 MOF。研究发现，MOF 用于两个主要领域的 LED 组件，即白色磷光体和发光层。用于发光层的 MOF 因有机连接体、金属及其相互作用（如 MLCT 或 LMCT）的存在而表现出电致发光。几个 MOF 显示出客体分子的电致发光。MOFs 广泛用于 LED 的主要障碍是能源效率、缺乏红光和稳定性。已经引入了克服这些障碍的研究。基于这些研究，我们为基于 MOF 的 LED 研究人员应考虑的当前挑战和各种观点提供了可能的解决方案。
