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[l,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[l,2-b:3,4-b']dithiophene(BDT)-thienothiophene (BDT-TT) based polymer is discussed. La présente invention concerne des compositions, la synthèse et des applications pour des polymères à base de benzo[1,2-b:3,4-b']dithiophène(BDT)-thiénothiophène (BDT-TT) dérivatisés en présence de furane, de thiophène et de sélénophène, à savoir, le poly[(4,8-bis(5-(2-éthyhexyl)sélénophén-2-yl)-benzo[1,2-b;4,5-b']dithiophène)-2,6-diyl-alt-(4-(2-éthylhexanoyl)-3-fluorothiéno[3,4-b]thiophène)-2-6-diyle (CS-15), le poly[(4,8-bis(5-(2-éthyhexyl)sélénophén-2-yl)-benzo[l,2-b;4,5- b']dithiophène)-2,6-diyl-alt-(4-(2-éthylhexyl)-3-fluorothiéno[3,4-b]thiophène)-2-carboxylate-2-6-diyle (CS-16), le poly[(4,8-bis(5-(2-éthyhexyl)furane-2-yl)-benzo[1,2-b;4,5-b']dithiophène)-2,6-diyl-alt-(4-(2-éthylhexyl)-3-fluorothiéno[3,4-b]thiophène)-2-carboxylate-2-6-diyle (CS-18) et le poly[(4,8-bis(5-hexylfuran-2-yl)-benzo[1,2-b;4,5- b']dithiophène)-2,6-diyl-alt-(4-(2-éthylhexanoyl)-3-fluorothiéno[3,4-b]thiophène)-2-6-diyle (CS-24). Une cellule solaire organique constituée d'un polymère à base de benzo[l,2-b:3,4-b']dithiophène(BDT)-thiénothiophène (BDT-TT) dérivatisé est en outre décrite.
