Aluminum is the third abundant element in the lithosphere and its compounds are widely dispersed and used in the environment around us in modern society: in water treatment, in food additives, in medicine, as the production of light alloy etc. Aluminum toxicity causes bone and joint diseases neuronal disorder leading to dementia myopathy and Alzheimer’s disease. Development of fluorescent chemosensors has currently attracted significant interest because of their potential application in medicinal and environmental research. Among several methods for the detection of Al3+ in the literature, spectrofluorimetry is widely used for its high sensitivity, selectivity and easy operation procedure. Herein we synthesized and characterized compound 1 obtained by condensing 2-hydroxynapthaldehyde with 3-(1-aminopropyl)imidazole. Compound 1 is used as an efficient fluorescent probe for the detection of Al3+ in EtOH and 5% water in EtOH.
