Bile Salts in Supramolecular Chemistry: Synthesis of Fluorescent Nanoclusters, Oxide Nanoflowers, and Anion Effect on Metallogels

Abstract

In summary, we have explored an interesting pH-dependent sensitization of Tb(III) using methyl salicylate (MS) as a sensitizer in aqueous media. Methyl salicylate was found to be a specific sensitizer for Tb(III) but not for Eu(III). Upon doping Eu(III) in Tb(III)-MS system resulted in the color change from green to orange depending upon the pH of the solutions. Photophysical studies confirm the energy transfer from Tb(III) to Eu(III) in the lanthanide mixed Tb(III)/Eu(III)-MS system
