Synthesis of multi-emission MOF composites for multi-dimensional sensing application

In recent years, multi-dimensional sensing methods based on multi-emission MOFs have attracted great attention from researchers due to their excellent sensitivity and selectivity to the target analytes. Through the mixed ligand strategy or encapsulating the appropriate fluorophores (lanthanide ions, luminescent ligands, metal ligand complexes, organic dyes, carbon dots, etc.) in the MOFs channel, MOF-based proportional sensors with multiple luminescent centers can be successfully designed. In this paper, the research progress of multi-dimensional sensors based on MOFs in recent years is reviewed, with emphasis on the preparation of three-emission MOF composites and their applications in detecting ions, pH, volatile organic compounds and organic molecules. This paper will be of great significance for researchers interested in multi-dimensional sensing based on three-emission MOFs to understand its research progress.
