Abstract
In recent years,fluorescent probes constructed from metal-organic frameworks(MOFs)have attracted considerable attention due to their excellent performance in the field of sensing.These fluorescent probes not only effectively compensate for many shortcomings of traditional detection techniques but also possess notable advantages such as low cost,ease of operation,high visualization,and high sensitivity,making them widely used in sensing technology research.This paper systematically reviews the recent domestic and international research progress on the application of MOFs and their composites as fluorescent probes in ion sensing.The design strategies,structural characteristics,luminescent properties,and sensing mechanisms of MOFs and their composite fluorescent probes are elaborated in detail,and an in-depth analysis and outlook on the future development trends of MOF-based fluorescent probes are provided.
