描述了在下缘用四个氧化还原活性四硫富瓦烯（TTF）部分取代的杯[4]芳烃支架的合成。该组装体强烈结合钠阳离子，并且结合过程伴随着受体的构象变化，如 NMR 滴定和复合物上的 X 射线衍射所示。这种动态行为显着导致 TTF 探针电化学响应的改变，该探针在钠络合后表现独立。 (C) 2010 Elsevier Ltd. 保留所有权利。
The synthesis of a calix[4]arene scaffold persubstituted with four redox-active tetrathiafulvalene (TTF) moieties at the lower rim is described. This assembly strongly binds sodium cation, and the binding process is accompanied by a conformational change of the receptor, as shown from NMR titration and by an X-ray diffraction led on the complex. This dynamic behavior remarkably results in a modification of the electrochemical response of TTF probes, which behave independently after sodium complexation. (C) 2010 Elsevier Ltd.
