Abstract
Synthesis and characteristic properties of polymers P1–P4 containing 1,3,4,6-tetraarylated pyrrolo[3,2-b]pyrrole-2,5-dione (isoDPP) units in the main chain are described. P1 and P2 were prepared upon palladium-catalyzed polycondensation of 3,6-bis(4-bromophenyl)-1,4-bis(4-tert-butylphenyl)pyrrolo[3,2-b]pyrrole-2,5-dione (M1) or 1,4-bis(4-bromophenyl)-3,6-bis(4-tert-butylphenyl)pyrrolo[3,2-b]pyrrole-2,5-dione (M2) and 2,2′-(9,9-dihexyl-9H-fluoren-2,7-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) (M4), while P3 and P4 were synthesized upon polycondensation of 3,6-bis(5-bromothien-2-yl)-1,4-bis(4-dodecylphenyl)pyrrolo[3,2-b]pyrrole-2,5-dione (M3) and 2,5-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)thiophene (M5) or 9-(2-ethylhexyl)-2,7-bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)carbazole (M6). Deeply colored polymers with molecular weights between 3.5 and 22 kDa were obtained. The polymers were soluble in common organic solvents such as dichloromethane, chloroform, and tetrahydrofuran.
