Crystal Engineering in Two Dimensions: Friction and Ferroelectrics

Abstract

Langmuir films of novel amphiphiles that present reversible collapse and two immiscible liquid phases are reported. The amphiphiles are distinguished by very large "bulge" groups that are significantly larger than the amphiphile chain. Brewster Angle Microscopy studies and absorption isotherms are used to demonstrate these findings. A major theoretical advance is reported using a solid state approach through mean field theory to model all observed solid like phases of Langmuir films of alkanoic acids or alcohols. Adaptation of the model amphiphiles to form molecules for formation of self-assembled monolayers with controlled frictional properties was unsuccessful.
