چکیده

Regioregular conjugated polymers containing alternating pyridyl[2,1,3]thiadiazole (PT) and indacenodithiophene (IDT) structural units were synthesized. In these copolymers, the pyridyl nitrogen atoms on PT are precisely arranged along the backbone so that each one has an adjacent proximal and an adjacent distal counterpart across the two IDT flanking units. We find that despite the absence of obvious differences in orbital energy levels and optical bandgap, the regioregular materials exhibit larger charge carrier mobilities, as determined by using field effect transistor devices, and can yield higher solar cell power conversion efficiencies when mixed with fullerenes in bulk heterojunction active layers.

Regioregular copolymers of 3-alkoxythiophene and their photovoltaic application.

Low band gap conjugated polymers with proper energy levels for charge transfer are required to achieve high-efficiency polymer solar cells. We report the synthesis and characterization of two new regioregular copolymers that are based on 3-alkoxythiophene monomers: poly(3-octylthiophene-2,5-diyl-co-3-decyloxythiophene-2,5-diyl) (POT-co-DOT) and poly{(9,9-dioctylfluorene)-2,7-diyl-alt-[4,7-bis(3...

reduction of steric hindrance between the solubilising alkyl groups and adjacent thiophene rings. The improved crystalline structure of PSBTBT resulted in a higher charge carrier mobility and improved solar cell performance in blends with fullerene derivatives. Low band gap co-polymers containing silafluorene, 40 dithieno[3,2-b:2′,3′-d]silole 7 and silaindacenodithiophene have recently demonstr...
