[Display omitted] • A novel NIR chemosensor BDDH based on isophorone was synthesized and characterized. • BDDH showed selectivity and sensitivity responses to Al3+ with fluorescence enhancement and color change. • The limit of detection (LOD) for Al3+ was reached the level of 10−8 M. • BDDH was applicated in identification of Al3+ in the different water samples. • BDDH was applicated in cell imaging in alive MCF-7 cells and plant imaging in soybean roots. In this paper, an isophorone-based NIR fluorescent and colormetric probe BDDH for Al3+ was synthesized and characterized, it showed highly selectivity and sensitivity through significant fluorescence enhancement and visible color change towards Al3+. The job plot confirmed that the binding ratio of BDDH with Al3+ was 1:1. Furthermore, the limit of detection (LOD) of Al3+ was determined to be 4.01 × 10−8 M. Moreover, BDDH was successfully applicated in identification of Al3+ in the different water samples, cell imaging in alive MCF-7 cells and plant imaging in soybean roots. [ABSTRACT FROM AUTHOR]

A new chemosensor L based on the naphthalimide moiety was synthesized and characterized. L exhibited the high selectivity and sensitivity for Al 3 + in CH 3 OH, 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 -Al 3 + complex was formed with an association constant of 7.6 × 10 4 M − 1 , and the limit of detection for Al 3 + was determined as 6.9 μM. In addition, L was successfully applied to the determination of Al 3 + in real water samples. [ABSTRACT FROM AUTHOR]
