The exploration of advanced fluorescent probes that can detect divalent copper (Cu2+) in aqueous environments and even in live organisms is particularly valuable for understanding the occurrence and development of Cu2+-related diseases. In this work, we report the design and synthesis of an aggregation-induced emission luminogen (AIEgen)-based probe (TPE-Py-EEGTIGYG) by integrating an AIEgen, TPE-Py, with a peptide, EEGTIGYG, which can selectively detect Cu2+ in both aqueous solution and live cells. Peptide EEGTIGYG has dual functionality in the probe design, namely improving water solubility and providing specific cell membrane-binding ability. TPE-Py-EEGTIGYG can self-assemble into nanoaggregates at high concentration in aqueous solution (e.g., 25 μM), which possess large fluorescence output due to the restriction of intramolecular rotation of the phenyl rings on TPE-Py. The fluorescence of the TPE-Py-EEGTIGYG nanoaggregates can be significantly quenched by Cu2+ but not by other metal ions, achieving the selective detection of Cu2+ in aqueous media. Furthermore, TPE-Py-EEGTIGYG can exist as a molecular species and is very weakly fluorescent in dilute aqueous solution (e.g., 5 μM), but can however largely switch on its fluorescence upon specifically anchoring onto the cell membrane. The emissive probes on the cell membrane can be used for the detection of Cu2+ ions that move in and out of cells with a fluorescence “turn-off” mode.

A novel fluorescent rhodamine-based probe L for selective responding to ClO– has been synthesized and characterized. The spectroscopy showed that probe L can detect ClO– in aqueous solution without interaction with other interfering ions, and the detection is also evident by the colour change from colourless to reddish purple under white light. The remarkable fluorescence enhancement showed the high selectivity and sensitivity of probe L for the detection of ClO–. Furthermore, probe L was applied to intracellular fluorescent imaging of HeLa cells treated with ClO– and MTT assay showed nontoxicity in living cells.
