■ Abstract : New Synthetic Methods for Accessing Tailored Macromolecules and Functionalized Carbons

This presentation will be divided into two parts. The first part will describe the use of various stimuli, including light and redox processes, to externally control various chemical transformations and polymerization reactions. These efforts have included the design and deployment of specially designed catalysts that contain photo and/or redox responsive units and are expected to facilitate access to polymeric materials with tailored structures, properties and functions. The second part of the presentation will focus on the synthesis and applications of contemporary carbon-based materials. We and others have found that the chemical potential intrinsic to graphite oxide (GO) and other forms of functionalized carbons may be harnessed to facilitate a wide range of useful transformation including oxidations, hydrations, and dehydrations, as well as various ionic oxidative, and acid-catalyzed polymerizations. In addition to displaying such broad reactivity, carbon-based catalysts also often offers a number of practical advantages as their heterogeneous nature can facilitate separation and purification procedures. The development of GO and related materials as catalysts for use in various synthetic transformations will be discussed, including those of potential commercial importance. Portions of the work to be described were supported by the Office of Naval Research and the Institute for Basic Science (IBS-R019-D1).
