Diketopyrrolopyrrole (DPP) is a component of large number materials used for optoelectronic applications. As it exclusively in combination with aromatic donors, the properties its homopolymers are unknown. Because donor–acceptor character has been shown other systems to reduce bandwidths, DPP should have even larger conduction bands and better n-type conductivity than thiophene-flanked systems,...

Three efficient synthetic approaches towards new azomethine- and terpyridine-containing 2,5-dihydropyrrolo[3,4-c]pyrrole-1,4-dione (diketopyrrolopyrrole, DPP) based polymers, such as P1 P2, are reported. The first approach involves the Pd-catalyzed synthesis via two- or three-component Suzuki Stille cross-coupling reaction in solution. second under ball-milling conditions. And, finally, third P...

A new diketopyrrolopyrrole (DPP)-containing donor-acceptor polymer, poly(2,5-bis(2-octyldodecyl)-3,6-di(furan-2-yl)-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione-co-thieno[3,2-b]thiophene) (PDBF-co-TT), is synthesized and studied as a semiconductor in organic thin film transistors (OTFTs) and organic photovoltaics (OPVs). High hole mobility of up to 0.53 cm(2) V(-1) s(-1) in bottom-gate, top-cont...
