Hg2+ detection by new anthracene pendant-arm derivatives of mixed N/S- and N/S/O-donor macrocycles: Fluorescence, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and density functional theory studies
Abstract
<p>The optical response of four new anthracenylmethyl pendant-arm derivatives (L1-L4) of the macrocyclic ligands [12]aneNS<sub>3</sub>, [12]aneNS <sub>2</sub>O, [15]aneNS<sub>2</sub>O<sub>2</sub>, and [12]aneN<sub>2</sub>SO toward the metal ions Zn<sup>2+</sup>, Cd<sup>2+</sup>, Pb<sup>2+</sup>, Cu <sup>2+</sup>, Hg<sup>2+</sup>, Ag<sup>+</sup>, Fe<sup>2+</sup>, Co <sup>2+</sup>, Ni<sup>2+</sup>, Mn<sup>2+</sup>, Ca<sup>2+</sup>, Na <sup>+</sup>, Mg<sup>2+</sup>, and K<sup>+</sup> was investigated in 1:1 (v/v) MeCN/H<sub>2</sub>O solutions. A strong chelation enhancement of quenching effect was observed on the fluorescent emission intensity of L2 as a consequence of the host-guest interaction with Hg<sup>2+</sup> and the formation of a 1:2 metal-to-ligand complex. Density functional theory calculations confirmed the formation of a sandwich-type complex between L2 and Hg<sup>2+</sup> as a favorable process. A matrix-assisted laser desorption/ionization (MALDI) time-of-flight mass spectrometry study using the four ligands as active MALDI probes was also performed. L1-L4 have also been explored as fluorescence chemosensors in microsamples using NANODROP technology.</p>
