摘要

A new bis-calix[4]arene platform (4) formed by upper rim upper rim linking of two calixarene units has been obtained by 1:1 condensation of diformyl calixarene with carbohydrazide. The synthesized bis-calixarene has been found to selectively sense Fe3+, without interference from ferrous or any other metal ion through enhancement in the fluorescence intensity as well as ratiometric absorption changes accompanied by a color change. The importance of a bridged macro cyclic framework has been further highlighted by comparison with an acyclic reference compound. (C) 2014 Elsevier Ltd. All rights reserved.
