A new calix[4]pyrrole type anion receptor (1) containing two anti-symmetrically meso-situated acenaphthenequinone moieties has been constructed by a “one-pot” facile synthesis. The crystal structures of 1 and 1·F − complex were characterized by X-ray crystallography. The crystal of 1·F − complex witnessed that a CH group from the acenaphthenequinone participated in anion binding through...
Two redox anion receptors based on calix[4]pyrrole and ferrocene have been synthesized. The electrochemical investigation revealed that these compounds can be response to the anions with different shifts of Fc/Fc + couple. With the 1 H NMR titration study, the selectivity to F − and AcO − ions in CD 3 CN solution was confirmed. The conformations of the mono-aromatic...
