1H and 13C NMR spectra were recorded on a Bruker-400
spectrometer with tetramethylsilane as the internal standard.
ESI-MS spectra were performed on a Bruker esquire HCT-
Agilent 1200 spectrometer. Fluorescence spectra were taken
on a Hitachi F-7000 fluorescence spectrometer. UV-vis absorp-
tion spectra were recorded on a TU-1901 spectrophotometer.
X-ray diffraction data collection was performed on Gemini
A Ultra diffractometer. Images of cells were obtained using
an Olympus FV1000 confocal laser scanning microscope.

Synthesis of (E)-N’-((2-hydroxynaphthalen-1-yl)
methylene)nicotinohydrazide (HNN)
[6] T.-J. Jia, W. Cao, X.-J. Zheng, L.-P. Jin, Tetrahedron Lett. 2013, 54,
A solution of 2-hydroxy-1-napthaldehyde (0.50 g, 2.9 mmol)
and nicotinohydrazide (0.41 g, 3.0 mmol) was stirred at 728C in
methanol (30 mL) under a nitrogen atmosphere until complete
consumption of 2-hydroxy-1-napthaldehyde was observed by
TLC monitoring (,10 h). The reaction mixture was cooled to
room temperature to give a precipitate. The precipitate was
collected by filtration and washed three times with cooled
methanol to afford HNN as a yellow solid (0.55 g, 65 %). The
solution of HNN in ethanol was allowed to evaporate slowly at
room temperature for several days and needle-like crystals
suitable for X-ray crystallography were formed.

Methods for Cell Imaging
Chang liver cells were incubated with HNN (10 mM) in the
absence and presence of Al3þ (10 mM) at 378C. After incubation,
the cells were washed with phosphate-buffered saline three
times before imaging. The images of cells were obtained using a
confocal laser scanning microscope.
