Abstract: A tetranuclear cyclometalated palladium-azo complex(MOP) was synthesized according to our previous work and applied as a differential colorimetric molecular chemosensor for organophosphorus pesticides(OPPs) for the first time. This molecular probe was found to have selective recognition ability to OPPs. In a DMF-acetone mixed solvent, it showed no spectral response to oxophosphate pesticides, but exhibited differential absorption spectra in the presence of different sulfur phosphorus pesticides(SPPs). In MOP sensing solutions, concentrations of different SPPs could be detected down to a level of 10-3 g/L by spectrophotometry, which could be used for the determination of SPPs.

Key words: Cyclometalated palladium-azo complex, Organophosphorus pesticides(OPPs), Detection
