| dc.description.abstract | Three donor-acceptor (D-A) alternating copolymers were synthesized using 4,8-bis(5-bromothiophen-2-yl)-6-octyl-5H-[1,2,5]thiadiazolo[3,4-f]isoindole-5,7(6H)-dione; 4,8-bis(5-bromothiophen-2-yl)-2-(2-ethylhexyl)-6-octyl-[1,2,3]triazolo[4,5-f]isoindole-5,7(2H,6H)-dione and 4,8-bis(5-bromothiophen-2-yl)-2,6-dioctyl-[1,2,3]triazolo[4,5-f]isoindole-5,7(2H,6H)-dione as acceptor monomers and 4,8-bis(5-(2-ethylhexyl)thieno[3,2-b]thiophen-2-yl)benzo[1,2-b:4,5-b’]dithiophene-2,6-diyl)bis(trimethylstannane) as a donor monomer by Stille coupling polymerization reactions. The resulting copolymers possessed good solubility in common organic solvents such as chloroform and o-dichlorobenzene. These copolymers were characterized using UV-Vis spectrometry and cyclic voltammetry. In addition, a PDI-based acceptor 11,11'-(9,9'-spirobi[fluorene]-2,7-diyl)bis(2,8-bis(2-ethylhexyl)-1H-pyrido[3',4',5':4,5]naphtho[2,1,8-cde]- pyrido[3',4',5':4,5]naphtho[8,1,2-ghi]isoindole-1,3,7,9(2H,5H,8H)-tetraone) was synthesized via modified Suzuki coupling reaction. | en_US |
