A new fluorescent probe 1 (P1) for Cu2+ based on rhodamine B was designed and synthesized. P1 exhibits high sensitivity and selectivity for sensing Cu2+ and color changes from colorless to pink in aqueous media. Selective fluorescent enhancement of P1 was attributed to ring-opening from the spirolactam (nonfluorescent) to ring-opened amide (fluorescent). A chemosensor based on rhodamine B has a good potential application to the determination of Cu2+ in environmental and biological systems.
⺠This work designed and synthesized a new fluorescent probe (P1) based on rhodamine B derivative. ⺠The probe showed high selectivity for Cu2+ over other metal ions and color change from colorless to pink in aqueous solution. ⺠Based on the specific response of P1 toward Cu2+, a novel fluorescent probe for the determination of Cu2+ was developed.
