New potential materials for polymer solar cells contg. ruthenium bipyridine complexes as photosensitizing dyes were synthesized. The 4'- Me functionality of 4,4'-Dimethyl-2,2'-bipyridine was derivatized to form 3-hydroxypropyl, which was then reacted with methacryloyl chloride to add an acrylate functionality, then co-polymd. with Me methacrylate monomer to leave a polymeric dangling group on the bipyridine. This was then added into dimethoxy Ruthenium bipyridine complexes and dimethoxy Ruthenium di(1,10)-phenanthroline complexes. Proton NMR was used to verify structure of some intermediates, and UV-VIS spectroscopy was used to verify incorporation into the ruthenium complexes. Cyclic voltammetry was performed and current-potential relationships of the copolymers are presented in graphical form. This overall approach led to polymers that display favorable absorption and luminescence as well as electrochem. properties for photovoltaic device applications
