The compound not only could be used as an electrochemical probe for Cu2+ with an anodic peak shift of Fe(II)/Fe(III) redox couple, but also could be a colorimetric and fluorescent probe due to the detectable change in color by naked eyes and a significant fluorescence quenching of monomeric anthracene moiety. This highly selective sensing of Cu2+ may be attributed to the unprecedented intermolecular electron-transfer reorganization after the oxidation of the first single electron of compound 5, as indicated by electrospray ionization mass spectrometry(ESI-MS) and density functional theory(DFT) calculation results. To the best of our knowledge, this class of compounds have rarely been reported in the field of molecular sensing. It may have a potential significance for the application of the ferrocenyl-isoxazole derivative in molecular recognition.展开更多
