摘要
A new, highly selective and sensitive colorimetric chemosensor 1 for detection of Cu2+ ions in aqueous solution was developed. Receptor 1 detected Cu2+ ions by changing its color from colorless to yellow. Moreover, the Cu2+-sensitive compound was used as a colorimetric pH detector based on a color change due to 1-Cu2+ complex formation identifiable by the naked eye.
