New calix[4]arene based oxalylamido receptors for recognition of copper(II)
摘要:
New calix[4]arene derivatives with oxalylamido loops on their upper and lower rim (7, 8) have been designed and synthesized. It has been determined that molecular receptor 8 is more efficient than 7 for recognition of copper ions in preference to other metal ions through distinct 'naked eye' color change and a significant change in absorption spectra and fluorescence characteristics. The reported work paves the way for development of novel sensor materials for ubiquitous ions like copper at low concentrations. (C) 2013 Elsevier Ltd. All rights reserved.
