  Selective recognition of Zn2+ by salicylaldimine appended triazole-linked di-derivatives of calix[4]arene by enhanced fluorescence emission in aqueous-organic solutions: role of terminal –CH2OH moietieefs in conjunction with the imine in recognition

  摘要：

  A series of lower rim 1,3-di-derivatives possessing Schiff's base cores were synthesized using triazole unit as linker moiety by further introducing butyl (L-2), one -CH2CH (L-3) and two -CH2OH (L-4)-containing moieties, respectively, in order to bring additional support for ion binding. Based on fluorescence and absorption spectroscopies it has been shown that Zn2+ Could be selectively recognized by the Schiff's base core and not by the triazole core among the ten metal ions studied both in methanol and in aqueous Solutions of methanol and acetonitrile, wherein the -CH2OH moieties augment the fluorescence response by providing additional coordinations to the Zn2+. Thus L-4 exhibited a fluorescence enhancement of similar to 65, similar to 48 and similar to 25-fold in methanol. aqueous Solutions of methanol and acetonitrile. with minimum detection limits of 174. 3 13 and 320 ppb, respectively. Both the excitation and emission wavelengths fall in visible region. (C) 2009 Elsevier Ltd. All rights reserved.
