-Abstract-
The self-assembly of molecules into nano-structured materials is a fascinating process because small changes in intermolecular interactions can have a large impact on the final mesoscopic structures. An interesting goal is the directed self-assembly of molecules where the chemical nature of the molecules is altered to drive the assembly into specific nanostructures. In this talk I will discuss two classes of molecules: -peptides and Gemini surfactants. In the former, some sequences assemble into long hollow cylinders, but other similar sequences do not. The latter form lyotropic liquid crystalline phases. Using computer simulation I will show that interactions between three molecules play an important role in the assembly of -peptides and electrostatic interactions play an important role in the self-assembly of Gemini surfactants. Both systems are promising candidates for chemistry directed self-assembly.
