(TTF=tetrathiafulvalene) receptors incorporating amide binding units for anion recognition have been synthesized and characterized. For this purpose, two synthetically versatile new TTF carboxylic acid derivatives were prepared and characterized by X-ray diffraction, these structures demonstrating the critical role of the carboxylic function in the solid-state organization. Some of the calixarene–amide–TTF
已经合成并表征了一系列结合酰胺结合单元以识别阴离子的杯芳烃-TTF(TTF =四硫富瓦烯)受体。为此,制备了两种合成上通用的新型TTF羧酸衍生物,并通过X射线衍射对其进行了表征,这些结构证明了羧酸官能团在固态组织中的关键作用。某些杯芳烃-酰胺-TTF组件显示出很强的各种阴离子的结合,如图1项1 H NMR滴定研究,和一种受体是能够在H的存在下,电化学响应2 PO 4 -,C 6 H ^ 5 CO 2 -或CH 3 CO2 -阴离子。
