Photo/electrochemical sensing technology currently shows significant application potential in medical diagnostics, environmental monitoring, and food safety, gradually becoming a research focus in recent years. Novel materials with high photo/electroactivity, environmental friendliness and controllable structures are urgently needed. Metal−organic frameworks (MOFs) have attracted considerable interest because of their high specific surface area and adjustable structures. Integrating porphyrin molecules into MOF structures to form porphyrin-engineered MOFs can effectively suppress the self-aggregation of porphyrin molecules and enhance their photoelectric properties. Therefore, these materials are highly favored in photo/electrochemical sensing applications. This review details the types and preparation methods of porphyrin-engineered MOFs, including porphyrin MOFs, porphyrin@MOFs, and porphyrin-engineered MOF composites. Then, we summarize the mechanisms of porphyrin-engineered MOFs in photochemical sensing, electrochemical sensing, electrochemiluminescence sensing, photoelectrochemical sensing, and photo/electrochemical dual-mode sensing. Finally, we explore the prospects, challenges and opportunities for porphyrin-engineered MOFs in photo/electrochemical sensing applications. This review provides a valuable perspective for the preparation and sensing applications of multifunctional nanomaterials.
