In this study, a novel chemosensor (HL) for Al3+ which contains rhodamine and naphthalene moieties has been designed and synthesized. In the presence of Al3+, the receptor exhibited a strong, increasing fluorescent emission centered at 550 nm at the expense of the fluorescent emission of HI-centered at 520 nm. We proposed that the addition of Al3+ triggered intramolecular fluorescence resonance energy transfer (FRET) from naphthalene to Rhodamine 6G. (C) 2016 Elsevier Ltd. All rights reserved.
