title: A highly selective and sensitive rhodamine-derived fluorescent probe for detection of Cu2.
abstract: A novel water-soluble and reversible fluorescent probe was designed and synthesized based on a rhodamine B derivative. It was used for detection of Cu2+in drinking water and in living cells with high sensitivity and excellent selectivity. The tested concentration range and the limit of detection (LOD) of the probe were 0-15.00μmolL-1and 0.085μmolL-1, respectively. In addition, the mode of binding and mechanism of interaction between the probe and Cu2+were analyzed by density functional theory (DFT) calculations.
