| description | Nickel ions are toxic to the environment and they are also relevant in biology. Fluorescence sensing is a sensitive method and metal
sensing can be carried out employing cheaper and easy-to-synthesize molecules that possess fluorescence emission. Therefore, the
development of newer and simply-synthesized chemosensor molecules for nickel ions in aqueous media is required. We report, in this
paper, a simple semicarbazone derivative of a piperidin-4-one as a nickel ion sensor in water. The compound forms a 1:1 stoichiometric
complex with nickel ions. The association constant value is 4.04 × 104
mol-1
dm3
. The nickel ion-selectivity of the compound is explored
employing UV-Vis and fluorescence spectroscopy. Ni2+ ion-chelation enhances the fluorescence of the chemosensor molecule. The Ni2+
detection limit of the chemosensor was 1 × 10-7 mol dm-3
. The compound also forms a 1:2 inclusion complex with β-cyclodextrin. The
structure of the complex is proposed. Host: guest complex formation of β-cyclodextrin with the piperidin-4-one derivative results in the
interference of the host molecule with the chelation of Ni2+ ions. As an extension of the application of the piperidin-4-one derivative, we
demonstrate the Ni(II) ion filtration by incorporating the compound with a polysulfone film. |
