An efficient inclusion complex based fluorescent sensor for mercury (ii) and its application in live cell imaging
The formation of an inclusion complex between hydroxypropyl-Ξ²-cyclodextrin (H-CD) and 4-acetylphenyl-4-(((6-
chlorobenzo[d]thiazol-2-yl)-imino)-methyl)-benzoate (L) was investigated by FT-IR, 1
H-NMR, X-ray difraction (XRD),
FT-Raman, scanning electron microscope (SEM) techniques in the solid-state, absorption and emission spectroscopy in the
liquid state and the virtual state as molecular docking technique. The binding properties of the inclusion complex (H-CD:
L) with cations in deionized water was observed via absorbance and photoluminescence (PL) emission spectroscopy. The
fuorescence probe (H-CD: L) inclusion complex (IC) was examined for several heavy metal cations, and identifed that the
PL emission wavelength of the complex displayed a continuous rise in the fuorescence intensity for Hg2+. A linearity range
of 1Γ 10β8 β 11Γ 10β8 M and limit of detection value of 2.71Γ10β10 M was found to be achieved for the detection of Hg2+.
This outcome proves that the inclusion complex H-CD: L would be a promising material for the development a solid-state
fuorescence probe for detecting Hg2+. It also shows application in real sample analysis and cell imaging
