From one to three, modifications of sensing behavior with solvent system: DFT calculations and real-life application in detection of multianalytes (Cu2+, Ni2+ and Co2+) based on a colorimetric Schiff base probe

A rhodamine-based colorimetric sensor, RBOV has been synthesized and modified for selective detection of Cu2+, Ni2+ and Co2+ ions simultaneously in aqueous medium. The difference in color change upon binding with these three cations makes it an interesting multianalyte sensor. Furthermore, the detec...
