A simple asymmetric hydrazone 1 based on salicylaldehyde was designed and prepared, and exhibited an evident aggregation-induced emission (AIE) at a long wavelength of 570 nm in aqueous medium. Probe 1 can selectively sense Al in CHOH solution through the chelation-enhanced fluorescence mechanism and also recognize Cu via fluorescence quenching in HO solution through the Cu-induced assembly of aggregates. In addition, the probe can be applied for detecting Cu in biological samples.
