Mercury ions are considered as severe environmental pollutants as they are widely spread in the atmosphere and surface water from either natural or anthropogenic activities. Current practices in detecting the ions involve sophisticated and costly analytical techniques including atomic absorption spectrometry, atomic emission spectrometry and inductively coupled plasma/mass spectrometry. Fluorogenic chemosensors, on the other hand, offer the unique advantages of high selectivity, high sensitivity, long lifetime and relatively low costs. This study focuses on reviewing current development of fluorogenic chemosensors in mercury ions detection, based on the use of naphthalimide or non-naphthalimide derivatives. The design principles as well as photophysical properties for the fluorogenic chemosensors are discussed. This study concludes with future perspectives of chemosensor design, including employment of C=N isomerization mechanism for fluorescence improvement and utilization of crown ether for improved recognition of mercury ions.
