Zusammenfassung:Compositions, synthesis and applications for furan, thiophene and selenophene derivatized benzo[1,2-b:3,4-b′]dithiophene(BDT)-thienothiophene (BDT-TT) based polymers, namely, poly[(4,8-bis(5-(2-ethyhexyl)selenophen-2-yl)-benzo[1,2-b;4,5-b′]dithiophene)-2,6-diyl-alt-(4-(2-ethylhexanoyl)-3-fluorothieno[3,4-b]thiophene)-2-6-diyl (CS-15), poly[(4,8-bis(5-(2-ethyhexyl)selenophen-2-yl)-benzo[1,2-b;4,5-b′]dithiophene)-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene)-2-carboxylate-2-6-diyl (CS-16), poly[(4,8-bis(5-(2-ethyhexyl)furan-2-yl)-benzo[1,2-b;4,5-b′]dithiophene)-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene)-2-carboxylate-2-6-diyl (CS-18) and poly[(4,8-bis(5-hexylfuran-2-yl)-benzo[1,2-b;4,5-b′]dithiophene)-2,6-diyl-alt-(4-(2-ethylhexanoyl)-3-fluorothieno[3,4-b]thiophene)-2-6-diyl (CS-24) are disclosed. Further, an organic solar cell constructed of a derivatized benzo[1,2-b:3,4-b′]dithiophene(BDT)-thienothiophene (BDT-TT) based polymer is discussed.
