A new, highly selective and sensitive colorimetric chemosensor 1 for detection of Cu(2+) ions in aqueous solution was developed. Receptor 1 detected Cu(2+) ions by changing its color from colorless to yellow. Moreover, the Cu(2+)-sensitive compound was used as a colorimetric pH detector based on a color change due to 1-Cu(2+) complex formation identifiable by the naked eye.
一种新的、高选择性和高灵敏度的比色化学传感器 1 被开发出来，用于检测水溶液中的 Cu(2+)离子。受体 1 通过将其颜色从无色变为黄色来检测 Cu(2+)离子。此外，基于 1-Cu(2+)配合物形成导致的颜色变化，该 Cu(2+)敏感化合物可用作比色 pH 探测器，肉眼即可识别。
