Abstract

Calix[n]aryl esters 2_n (n=4 and 6) bearing two stable N-O·radicals on the lower rim are synthesized: in 2₆ the exchange interaction (El) changes in response to a metal-induced 1,2,3-alternate-to-cone conformational change but in 2₄ the metal-induced rotation of the carbonyl groups is not enough to change the El.
