Donor-acceptor-type polymers based on dithieno[2,3-b;7,6-b ]carbazole unit for photovoltaic applications

Dithieno[2,3-b;7,6-b]carbazole (TCZT), a type of heteropentacene with nitrogen and sulfur atoms, was synthesized with a focus on the unique reactivity of carbazole via double intramolecular Friedel-Crafts acylation. A donor-acceptor-type polymer (PTCZTBT)

SYNTHESIS OF 2,4-DIHYDROPYRROLOPYRROLES AND 4,6-DIHYDRO-2H-DIPYRROLOPYRROLES

The labile heterocyclic ring systems, 2,4-dihydropyrrolopyrrole 1 and 4,6-dihydro-2H-dipyrrolopyrrole 2, were prepared readily by the phosphineiminealkylidenemalonate cyclization reaction or the retro-malonate addition reaction.An X-
