摘要：

New calixarene based dual chromogenic receptors bearing isatin hydrazone units have been synthesized and evaluated for their ion recognition potential. The synthesized molecular receptors can effectively and selectively recognize fluoride and silver ions through visible color changes and pronounced bathochromic shifts in their UV-visible spectra. NMR titration data further support the preliminary conclusions. (C) 2013 Elsevier Ltd. All rights reserved.
