Benzo[1,2-c;4,5-c′]Bis[1,2,5]Thiadiazole in Organic Optoelectronics: A Mini-Review

In this paper, organic optoelectronic research activities in the field of benzo[1,2-c;4,5-c′]bis[1,2,5]thiadiazole (BBT)-based materials are reviewed. Synthetic pathways to the BBT core and its computational studies are described. Collective observations from separate reports suggest open-shell biradical nature of BBT-based materials. Future research directions for these materials are also described.
