The synthesis , spectroscopic and electrochemical properties of a series of donor-acceptor (DA) type polymers by changing the donor unit (thiophene, dithienopyrrole) polymer backbone were investigated.The synthesized CoP1 and CoP2 were designed to investigate the effect of copolymerization and insertion of perylene tetracarboxylic dimide (PDI) on the structure of benzotriazole (BTz) based polymers. For CoP1 1,7-dibromo-perylene diimide,4,7-dibromo-2-dodecyl-2H-benzo[d][1,2,3]triazole and 2,5 bis(tributylstannyl)thiophene coupled with Stille Coupling. For CoP2 1,7-dibromo-perylene diimide, 4,7-dibromo-2-dodecyl-2H-benzo[d][1,2,3]triazole 4-dodecyl-2,6-bis(tributylstannyl)-4H dithieno[3,2-b:2',3'-d]pyrrole coupled with Stille Coupling. The resultant donnor acceptor type random copolymer indicated that incorporation of PDI into the structure of BTz based polymers leaded to increase in the n-type properties. CoP1; BTz-Th donor-acceptor based conjugated polymers converted to only n-dopable material. CoP2 ; BTz-DTP donor-acceptor based conjugated polymers converted to ambipolar material.
