As an emerging optical material, perovskite nanocrystals (NCs) exhibit excellent optoelectronic properties and show great potential for various optoelectronic applications. However, the inherent inferior stability against moisture, oxygen, light and heat limit their practical application. As well, the exploration and development of perovskite NCs with novel properties and functions are new challenges. To achieve these goals, the integration and encapsulation of perovskite NCs with multifunctional metal-organic frameworks (MOFs) to form perovskite NC@MOF composites, is a promising strategy for enhancing the stability and broadening the application scope. In this minireview, we summarize and discuss the synthesis strategies and functional mechanisms of perovskite NC@MOF composites, along with applications of light emitting diodes (LED), information security, photocatalysis, sensing, and detection. We further briefly point out the current challenges as well as the future opportunities for the emerged composite materials.
作为一种新兴的光学材料，钙钛矿纳米晶体（NCs）展现出优异的光电性能，并在各种光电应用中显示出巨大潜力。然而，其固有的对水分、氧气、光和热的稳定性较差限制了它们的实际应用。此外，探索和开发具有新颖性质和功能的钙钛矿纳米晶体也是新的挑战。为实现这些目标，将钙钛矿纳米晶体与多功能金属有机框架（MOFs）整合和封装以形成钙钛矿NC@MOF复合材料，是提高稳定性和拓宽应用范围的一种有前景的策略。在这篇综述中，我们总结并讨论了钙钛矿NC@MOF复合材料的合成策略和功能机制，以及发光二极管（LED）、信息安全、光催化、传感和检测等方面的应用。我们还简要指出了这种新兴复合材料当前面临的挑战以及未来的机遇。
