Understanding the Role of Metal–Organic Frameworks in Surface‐Enhanced Raman Scattering Application

Abstract 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.
