摘要：

Surface pressure-molecular area isotherms of mixed Langmuir monolayer films of N-docosyl-N′-methyl viologen (C22MV2+) with arachidic acid were measured at the air/water interface and the electrochemical behavior of the 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 C22MV2+ converge with addition of arachidic acid and show a single peak at the mole ratio of viologen : arachidic acid = 1:3. © 1990.
