The precision arrangement of biologically interesting molecules on surfaces is a field in its infancy, especially for displays of different types of molecules on the same surface. It is our belief that a properly designed 'bottom-up' approach will allow the construction of nanometer-scale surface features with the exquisite control that is the norm in angstrom-scale organic synthesis. The design of this research is to synthesize 2-dimensional materials by aligning oligophenylacetylenes along the backbone of a linear polyimide. The novelty of the design is that consecutive 90 ° twist angles along the polyimide backbone will ensure that adjacent oligophenylacetylenes are held in the same plane.

The result of this research will be an 'artificial surface' in which diverse and variable types of functional groups can be separated by precise distances. In this poster presentation, progress in the synthesis, characterization, and application of functional surfaces will be described.
