Selective sensing of Cu (II) by a simple anthracene-based tripodal chemosensor
摘要:
A new and an easy-to-make simple tripodal shaped chemosensor 1 has been designed and synthesised for metal ions. In CH3CN containing 0.04% DMSO, upon excitation at 370nm, chemosensor 1 exhibited structured emission centred at 418nm, which increased to a significant extent upon complexation of Cu (II). The other metal ions except Zn2+ and Hg2+ examined in this study did not exhibit any marked change in emission of 1 under a similar condition. Although Cu2+ ion showed strong interaction with 1, Zn2+ and Hg2+ ions exhibited moderate binding.

A new and an easy-to-make simple tripodal shaped chemosensor 1, comprising an anthracene moiety as a fluorophore and amide, alcohol functionalities as ligating groups has been designed and synthesized for Zn(II). In CH3CN containing 0.1% DMSO, upon excitation at 370 nm, the chemosensor 1 exhibited an emission at 412 nm, which increased to a large extent upon complexation of Zn(II). Among the other metal ions examined in the study, Cd2+ moderately perturbed the emission of 1 under similar conditions. (C) 2010 Elsevier Ltd. All rights reserved.
