Session: ACS Award for Encouraging Women into Careers in the Chemical Sciences: Symposium Honoring Katherine Franz :

The development of new materials for use in fluorescent and phosphorescent organic light emitting devices (OLEDs and PHOLEDs) continues to inspire interest in organometallic complexes that have unique photophysical properties. Over the last several years, our group has been working on applying the tenets of Green Chemistry to existing literature protocols for various coupling reactions. Our primary goal has been to synthesize bi- and polyaromatic molecules for use as ligands in transition metal complexes while minimizing use of additives and formation of by-products. Recently, we have decided on a slightly different strategy: starting with known “greener” protocols, we are working to broaden the scope of these reactions and use them as a starting point for developing new synthetic routes to molecules that may lead to unexpected properties and chemical reactivity when coordinated to metals. To date, we have synthesized substituted α,β-diketones, quinoxalines, benzoquinoxalines, and pyrazines, and have completed some preliminary studies of their metal complexation reactions, all utilizing methods with enhanced adherence to the tenets of Green Chemistry. In this poster, we will present details of the syntheses, greener aspects of the reactions, and characterization of products.
