Small molecular fluorescent probe possess such advantages as high selectivity, high sensitivity and visualization when applied in detecting the pollutants. However, the drawback of low detection efficiency, difficulty to separate and recovery from bulk solution and pollution to the environment can notbe overcome. Small molecules fluorescent probes loaded on the surface of mesoporous materials by chemical methods can combine the advantages of fluorescent probes and mesoporous materials. The mesoporous material-based fluorescence probe can not only possess the function of detection and clearance of small molecular fluorescent probe, but also may achieve lower concentration detection and enhance the detection sensitivity by adjusting the pore size and components of mesoporous materials. This paper reviews the research progress of different mesoporous materials-based fluorescent probes firstly. The applications of different mesoporous materials-based fluorescent probes in the detection of heavy metal ions, organic small molecules, biological molecules and anions are elucidated emphasizedly. Lastly, the future studies for mesoporous materials-based fluorescent probes are also expected.
