✦ Synopsis

Three new electroactive ligands, 3a, 3b and 3c, that contain the biphenyl frameworks in their structure wm'e p~pared. These new ligande presented three interesting characteristics: 1) they exhibited a reversible oxidation, 2) the oxidation induced a conformational change in the crown moiety and 3) they had two different coordination centers, the crown ether and the dimethylamino groups. Electrochemical and spectroscopic studies using alkali, alkali-earth and mercury salts were canied out
