Headgroup Immersion Depth and Its Effect on the Lateral Diffusion of Amphiphiles at the

this paper, we describe a set of electrochemical experiments investigating lateral diffusion of several long alkyl chain amphiphilic ferrocene derivatives. We focus on the dependence of the lateral mobility on the length of the alkyl chains and on the polarity of the headgroups. In our electrochemical approach, we take advantage of "line" microelectrodes, which can be positioned in the plane of the air/water interface and which address electrochemically active species forming Langmuir monolayers at that interfac
