Abbott Department of Chemical and Biological Engineering, University of Wisconsin-Madison, 1415 Engineering Drive, Madison, WI 53706-1607, United States graphical a bstract ar ti c l e i nf o ab stra ct Article history: We report experiments that test the hypothesis that redox-triggered changes in the architectures of Received 4 March 2017 surfactants permit control of mixing of surfactants within assemblies. Speciﬁcally, we describe surface Revised 14 April 2017 tension, light scattering, atomic force microscopy, and quartz crystal microbalance measurements that Accepted 18 April 2017 characterize the redox-dependent behaviors of cationic surfactants with a ferrocene group located either Available online 19 April 2017 at the surfactant terminus (11-ferrocenylundecyl-trimethylammonium bromide; FTMA) or head (N,N-dimethylferrocenylmethyldecylammonium bromide; DMFA). In bulk solution, we ﬁnd that reduced Keywords: and oxidized FTMA do not mix within micellar assemblies but that reduced and oxidized DMFA do form Surfactant mixtures mixed micelles. Because oxidized FTMA has the architecture of a bolaform surfactant whereas
