Abstract

Compositions, synthesis and applications for benzene, furan, thiophene, selenophene, pyrole, pyran, pyridine, oxazole, thiazole and imidazole derivatized anthra[2,3-b:6,7-b′]dithiophene (ADT) based polymers, namely, poly{5,11-bis(5-(2-ethylhexyl)thiophen-2-yl)anthra[2,3-b:6,7-b′]dithiophene-2,8-diyl-alt-2-ethyl-1-(thieno[3,4-b]thiophen-2-yl)hexan-1-one-4,6-diyl}, poly{5,11-bis(5-(2-ethylhexyl)furan-2-yl)anthra[2,3-b:6,7-b′]dithiophene-2,8-diyl-alt-2-ethyl-1-(thieno[3,4-b]thiophen-2-yl)hexan-1-one-4,6-diyl and poly{5,11-bis(5-(2-ethylhexyl)selenophen-2-yl)anthra[2,3-b:6,7-b′]dithiophene-2,8-diyl-alt-2-ethyl-1-(thieno[3,4-b]thiophen-2-yl)hexan-1-one-4,6-diyl} are disclosed. Further, an organic solar cell constructed of a derivatized anthra[2,3-b:6,7-b′]dithiophene (ADT) based polymer is discussed.
