Transition metal binding properties of the redox-active 1,4,7,10,13,16-hexa(ferrocenylmethyl)- 1,4,7,10,13,16-hexaazacyclooctadecane and its electrochemical behaviour in a non-aqueous solvent

摘要

Solution studies to elucidate the coordination behaviour and the electrochemical response of the ferrocene-functionalized polyazamacrocycle 1,4,7,10,13,16-hexa(ferrocenylmethyl) 1,4,7,10,13,16-hexaazacyclooctadecane (L~1) by potentiometric methods and electrochemical techniques have been carried out. Potentiometric methods in the presence of Cd~(2+), Hg~(2+), Pb~(2+) and Zn~(2+) were carried out in 1,4-dioxane/water (70:30 v/v, 25 deg C, 0.1 mol dm~(-3) KNO_3). Electrochemical studies were carried out in acetonitrile /dichloromethane (50:50 v/v, 25 deg C, 0.1 mol dm~(-3) TBAClO_4) in the presence of transition metal ions and anions.
