HIGHLY SENSITIVE CHEMOSENSOR FOR Cu2+ AND Hg2+ BASED ON ANTHRACENE ANCHORED CALIX[4]ARENE PYRIDINE AMIDE RECEPTOR
In this study, anthracene anchored calix[4]arene pyridine amide (ant-CLX4) receptor was synthesized for the detection of Hg2+ and Cu2+ metal ions and fully characterized by spectroscopic methods. The ion binding properties of ant-CLX4 towards some selected metal ions such as Cu2+, Hg2+, Cr3+, CO2+, Ag+, Tb3+, Zn2+, Cd2+, Ni2+, Ga3+, Mn2+, Yb3+ and Gd3+ were studied by absorption and emission spectra. The ant-CLX4 demonstrated excellent fluorescence response with quenching mechanism (turn-off) in the presence of trace amount of Hg2+ and Cu2+ ions. This quenching response of ant-CLX4 receptor showing the possible binding interaction between ant-CLX4 receptor and metal ions was also observed by a fluorescence color change from bright blue to colorless in presence of metal ions as Hg2+ and Cu2+. Furthermore, the binding stoichiometry of ant-CLX4 with metal ions was confirmed a 1:1 (ant-CLX4-Hg2+ and ant-CLX4-Cu2+) binding model by Job’s Plot method. The detection limits of copper and mercury ions were calculated to be 3.8 x10(-7) M and 3.3 x10(-7) M with a satisfying level for the detection of such ions in the micromolar scale, respectively. This work showed that anthracene anchored calix[4]arene pyridine amide (ant-CLX4) receptor could be used as a member of family of highly sensitive synthetic chemosensor towards toxic ions as Hg2+ and Cu2+.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 15471-17-7. SDS of cas: 15471-17-7.
