A Linear 20-Metal Cd(II)−Nd(III) Nanocluster with Temperature-Dependent NIR Luminescence for the Excitation Wavelength-Controlled Detection of Aloe Emodin
A Cd(II)-Nd(III) nanocluster [Cd<sub>8</sub>Nd<sub>12</sub>L<sub>12</sub>(OAc)<sub>34</sub>(OH)<sub>6</sub>(H<sub>2</sub>O)<sub>2</sub>] (<b>1</b>) was constructed from the vanillin-type ligand 3-ethoxysalicylaldehyde (HL). It shows temperature-dependent NIR luminescence and is used to detect aloe emodin (AE) through the quenching and enhancement of Nd(III) emission, which is controlled by excitation wavelengths. The luminescence response behavior of <b>1</b> toward AE is described by <i>I</i><sub>Ex490 nm</sub>/<i>I</i><sub>Ex390 nm</sub> = A*[AE]<sup>3</sup> + B*[AE]<sup>2</sup> + C*[AE] + D, which can be employed to determine AE concentrations in CH<sub>3</sub>CN and fetal calf serum.
