Progress on Optical Probes for Hydrogen Sulfate Anion Sensing

The hydrogen sulfate plays an important role in biological and environmental areas and can contaminate the environment, which will cause harm to human body.Thus it is of primary importance to detect hydrogen sulfate with high selectivity and sensitivity.Among these methods for detection of hydrogen sulfate, the optical chemosensor based on molecular recognition is desirable with unique advantage.Anions optical sensing systems are predominantly attractive due to their simplicity, high degree of specificity, low detection limits, easy on-line analysis and especial colorimetric recognition and in situ detection.Herein, the progress during the last decades of optical chemosensors and probes for hydrogen sulfate based on the recognizing mechanism is summarized.The further research orientations are also prospected.
