Abstract
The synthesis of two-dimensional polymers (2DPs) is an emerging field with expected applications in nano-electronics, separation membranes, and memory storage devices. Unlike linear or branched polymers, 2DPs are defined as topologically planar sheets having a thickness consistent to their monomer species. This dissertation revolves around the synthesis, fabrication, and surface functionalization of a 2DP coined poly(carboxy fantrip).Chapter one focuses on the definition, synthetic approaches, and applications of 2DPs. Both natural and synthetic two dimensional (2D) materials are reviewed, including different polymerization approaches, transfer processes and, surface modifications. Chapter two reports the optimization of a 2D monomer, carboxy fantrip, and derivatized versions on a preparative scale. This chapter addresses inconsistencies from previous procedures increasing monomer yields from a few milligrams to hundreds. Synthetic strategies, both working and unsuccessful are reported, including experimental protocol and characterization of intermediates. Chapter three discusses new photo-polymerization strategies at the air/water interface, polymer deposition onto solid substrates, and covalent surface modifications of the resulting film. The results of these experiments are monitored and analyzed by Brewster angle microscopy (BAM), differential interference contrast (DIC) microscopy, high speed videography, and contact angle measurements.
