✦ Synopsis
Surface pressure-molecular area isotherms of mixed Langmuir monolayer films of N-docosyl-N'-methyl viologen (Cz2MV2+) with arachidic acid were measured at the air/waterinterface and the electrochemical behavior ofthe films were investigated after transfer to an indium tin oxide electrode in aqueous sodium perchlorate solution. The average molecular area in the mixed monolayer films negatively deviates from ideal additivity. Double voltammetric peaks for the first reduction wave of pure Cz2MVZ+ converge with addition of arachidic acid and show a single peak at the mole ratio of tiologen arachidic acid = 1: 3.
