Zinc ion (Zn2+) plays an essential role in many physiological processes of the organism, such as brain activities, gene transcription and immune function, as well as some pathological processes and so on, therefore selective recognition and detection of Zn2+ are of important biological significance. Fluorescence technology has unique advantages such as high selectivity, sensitivity, low cost, real-time and in situ monitoring, thus it has become one of the most important sensing technology for zinc ion and a hot topic area in recent years to imaging Zn2+ in cells. Herein, the latest progresses in the last 10 years of fluorescent molecular probes based on the small molecules for Zn2+ are reviewed. These important fluorescent probes are classified according to three different mechanisms action (PET, ICT and FRET). The design of molecular structure, sensing mechanism and biological applications of these probes are introduced. In addition, the structure and property relationships are elucidated. Finally, the problems and the developing trends in this field are also discussed.
