Thin
films research. Thin films of organic compounds are important in many areas of science and technology, ranging from optics and electronics, to the control of adhesion, lubrication and corrosion. The way molecules are organized in thin films is therefore interesting both in its own right, as an issue for fundamental study, and because it influences a film's properties and function in practical applications. Our research on thin films aims to understand how and why molecules organize themselves the way they do at two-dimensional interfaces, and also to develop new ways for controlling their organization. In a research program at WWU spanning nearly a decade, we have studied many different aspects of molecular ordering at surfaces. Currently our focus is on using liquid crystal solvents to control orientational order, polymorphism, chirality, and other structural properties.
