The electrophilic borylation of 2,5-diarylpyrazines
results in the formation of boron-nitrogen doped dihydroindeno[1,2-b]fluorene which can be synthesized via
mildly air-sensitive techniques and the end products handled readily under
atmosphereic conditions. Through transmetallation via diarylzinc reagents a series
of derivatives were sythesized which show broad absorption profiles that
highlight the versatility of this backbone to be used in organic solar cell
devices. These compounds can be synthesized in large yields, in alow number of
steps and functionalized at many stages along the way providing a large depth
of possibilities. Exploratory device paramaters were studied and show PCE of
