Organic Photovoltaics has been shown to be promising alternative energy resources.  Harvesting light from the sun also has the added benefit of being “green”.  The goal of the research work described here is to synthesize small molecules that can be used in organic photovoltaics to discover increased photovoltaic performance. A series of small molecular donor-acceptor dyads was prepared by multiple synthetic steps that involves Grignard Metathesis, bromination, carboxylation and esterification of 3,6-dibromo-9-phenylcarbazole, 3-bromophenanthrene and perylenediimide precursor.  Structural characterization and elemental compositions were performed using proton NMR, elemental analysis and single X-ray crystallography.  Photophysical properties of these dyads in solution and solid state will be performed.  The potential applicability as additives in organic photovolatics will be assessed.
