Lower-rim ferrocenyl substituted calixarenes: new electrochemical sensors for anions

By Philip A. Gale, Zheng Chen, Michael G.B. Drew, Jennifer A. Heath and Paul D. Beer


New ferrocene substituted calix[4 and 5]arenes have been prepared and the crystal structure of a lower-rim substituted bis ferrocene calix[4]arene (7) has been elucidated. The respective ferrocene/ferrocenium redox-couples of compounds 6 (a calix[4]arene tetra ferrocene amide) and 8 (a calix[5]arene pentaferrocene amide) are shown to be significantly cathodically perturbed in the presence of anions by up to 160 mV in the presence of dihydrogen phosphate
