Metal-organic frameworks (MOFs), built from organic linkers and metal ions/clusters, have emerged as highly promising materials for wide applications. Combining highly porous crystalline MOFs with the surface-enhanced Raman scattering (SERS) technique can achieve unprecedented advantages of high selectivity, high sensitivity, and expedience in analysis and detection. In this critical review, the aim is to present a comprehensive review of recent advances in understanding of the roles of MOFs in MOF-SERS systems, particularly their structure-to-property correlation. Key examples are selected from representative literature to illustrate critical concepts and the MOF-based property-dependent applications are particularly emphasized. Finally, the barriers, future trends, and prospects for further advances in MOF-SERS platforms are also discussed.
金属-有机骨架（MOFs）由有机配体和金属离子/簇构建而成，已成为具有广泛应用前景的极具前途的材料。将高多孔结晶 MOFs 与表面增强拉曼散射（SERS）技术相结合，可以实现分析和检测中前所未有的高选择性、高灵敏度和便捷性的优势。在这篇重要的综述中，旨在全面综述理解 MOFs 在 MOF-SERS 系统中的作用的最新进展，特别是它们的结构-性质相关性。从代表性文献中选择关键示例来说明关键概念，并特别强调基于 MOF 的性质依赖性应用。最后，还讨论了 MOF-SERS 平台进一步发展的障碍、未来趋势和前景。
