A new multifunctional chemosensor 1, (E)-2-(((2-hydroxynaphthalen-1-yl)methylene)amino)-1H-benzo[de]isoquinoline-1,3(2H)-dione, based on naphtalimide and naphthaldehyde was developed, which showed the fluorescence responses to trivalent metal ions (Ga3+, Al3+ and Cr3+). Sensor 1 detected and differentiated selectively trivalent metal ions Ga3+, Al3+ and Cr3+ by fluorescence enhancement at different...
A new Schiff-base sensor 1, based on fluorene and salicylaldehyde, has been prepared for the fluorescent detection of Ga3+ and Zn2+ by different emissions. The sensing behaviors of 1 with Ga3+ and Zn2+ were studied by using photophysical experiments, NMR titration, and ESI-mass spectrometry analysis. Moreover, turn-on fluorescence of 1 toward Ga3+ and Zn2+ caused by photo-induced electron transfer...
