Impressively, among competitive cations, the sensor can detect Al(III) and Fe(III) in a methanol\u2013water (9:1, v\/v) medium by changing its optical color and turning on fluorescence response. The low limit of detection (LOD) value (72 \u00b5M) and the sensor's reproducibility assure us about its practical applicability. The spirolactam ring opening in the presence of two target cations induces the luminescence character to the chemosensor, and the NMR spectrum validates this fact.
