Copillar[5]arene-rhodamine conjugate as a selective sensor for Hg<sup>2+</sup> ions
Saswati Ghosh Roy, Subhendu Mondal, Kumaresh Ghosh
Abstract
A new copillar[5]arene-coupled rhodamine probe <bold>1</bold> shows selective sensing of Hg<sup>2+</sup> ions over a series of metal ions in CH<sub>3</sub>CN by exhibiting color change of the solution as well as turn on fluorescence. It also shows interaction with Cu<sup>2+</sup> by exhibiting different color and spectral change. Tetrabutylammonium iodide distinguishes between Hg<sup>2+</sup> and Cu<sup>2+</sup> ions.
