Abstract: A series of novel π-conjugated copolymers based on 2,2′-bis(1,3,4-thiadiazole) (BTDz) have been developed. Among them, the BTDz-based donor–acceptor alternating copolymer with the (E)-1,2-di(3-(2-ethylhexyl)thiophene)vinylene donor unit (PBTDzTV) exhibited a high solubility and high crystallinity. PBTDzTVs favorably… read more here.
