A new chemosensor L based on the naphthalimide moiety was synthesized and characterized. L exhibited the high selectivity and sensitivity for Al3+ in CH3OH, along with colorimetric and fluorometric dual-signaling responses based on the joint contribution of the ICT and CHEF processes. A 1:1 stoichiometry for the L-Al3+ complex was formed with an association constant of 7.6 x 10(4) M-1, and the limit of detection for Al3+ was determined as 6.9 mu M. In addition, L was successfully applied to the determination of Al3+ in real water samples. (C) 2016 Elsevier B.V. All rights reserved.
