Calix[4]arenes containing ferrocene amide at the upper rim and methoxy or ethoxycarbonylmethoxy (ethyl ester) groups at the lower rim (5a, 5b and 5c) have been synthesized. It was found that tetramethoxy 5a and dimethoxy diethyl ester 5c were conformationally labile and existed in both cone and part
