AzaBenzannulated PDI (AzaBPDI) dyes were synthesized in high yields via a new reaction sequence involving an imine condensation followed by visible light-induced photocyclization. The large scope and efficiency of this alternative to the Pictet-Spengler reaction is demonstrated, and allows the easy preparation of dimeric AzaBPDI as potential non-fullerene acceptors for organic solar cells.

The Way

The electrophilic borylation of 2,5-diarylpyrazines results in the formation of boron-nitrogen doped dihydroindeno[1,2-<i>b</i>]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 2%.
