•Naphthalene benzimidazole conjugate has been synthesized and characterized.•Detection of Al3+ in aqueous media with high selectivity and sensitivity.•A fluorescence “turn-on” processes by a possible PET mechanism proposed.•Sensor is utilized to detect the Al3+ ions in sewage water samples.
Naphthalene benzimidazole conjugate bearing a hydroxyl group was synthesized. Its binding properties towards various metal ions were examined and it showed a high selectivity and sensitivity towards Al3+ ions in aqueous media. The recognition processes follows a photo induced electron transfer (PET) mechanism assisted with the restricted intramolecular C–C single bond rotation and are scarcely influenced by other coexisting metal ions. In addition, determination of Al3+ in a variety of sewage water samples was also determined.
