A new chemosensor (NANH) based on naphthyl moietywas synthesized with good selectivity and sensitivity towards Al3+ ions via the inhibition by operating through dual mechanisms like photo-induced electron transfer (PET) and excited-state intramolecular proton transfer (ESIPT). The synthesized NANH was validated by various techniques such as H-1, C-13 NMR and mass spectrum. While prominent fluorescent enhancement was observed from the NANH upon binding with Al3+ ions, however, other metal ions have not responded in the emission spectrum. Detection limit and association constant of NANH for Al3+ were calculated as 1.2 x 10(-7) M and 4.09 x 10(4)M(-1) by using fluorescence titrationmethod. Binding ratio (1:1) of NANH with Al3+ ions were proved by Job's plot and DFT studies. Furthermore, aluminium in variety of water samples was determined, and NANH could be used for biosensing of Al3+ in living cells. (C) 2020 Elsevier B.V. All rights reserved.
