Abstract

A highly selective and sensitive fluorescent sensor for Al³⁺ has been developed. The sensor shows great fluorescence turn-on upon binding Al³⁺ in complete water, giving strong blue emission. In addition, the sensor's turn-on exhibits excellent selectivity to the Al³⁺ cation, with only a slight interference from Zn²⁺. These findings suggest that the developed Al³⁺ sensor could be a useful molecular probe for practical applications.
