Abstract
The ionochromic properties of Crystal Violet Lactone(CVL), 3,3-bis(p-dimethylaminophenyl)-6-dimethylaminophthalate with metal cations were investigated. It showed interestingly ring open reaction with addition of several metal ions in CH3CN solution. Upon addition of Hg2+, the CVL shows a new peak around 603nm in its absorption spectra, and the color of solution changed from colorless to blue. Whereas other ions including Fe3+, Cu2+, Fe2+, Al3+ and so on induced basically weakly spectral change, which makes it promising application in Hg2+ sensor.
