A method of forming a polymer, the method begins by combining 4,7-bis(5-bromo-4-alkylthiophen-2-yl)-5-chloro-6-fluorobenzo[c][1,2,5]thiadiazole, [4-alkyl-5-[5-(trimethylstannyl)thiophen-2-yl]thiophen-2-yl]trimethylstannane, (3,3′-difluoro-[2,2′-bithiophene]-5,5′-diyl)bis(trimethylstannane), Pd2dba3 and P(o-tol)3 to form the polymer:
In this polymer R1 and R2 are independently selected from the group consisting of a straight-chain or branched carbyl, silyl, or hydrocarbyl, a branched or cyclic alkyl with 1 to 30 atoms, a fused substituted aromatic ring, and a fused unsubstituted aromatic ring; and the ratio of x is between 0.6 to 0.8 and y is between 0.2 and 0.4.
一种形成聚合物的方法,该方法首先将 4,7-双(5-溴-4-烷基噻吩-2-基)-5-氯-6-氟苯并[c][1,2,5]噻二唑、[4-烷基-5-[5-(三甲基锡基)噻吩-2-基]噻吩-2-基]三甲基锡、(3,3′-二氟-[2,2′-噻吩]-5,5′-二基)双(三甲基锡)、Pd2dba3 和 P(o-tol)3 形成聚合物:
在这种聚合物中,R1 和 R2 独立地选自直链或支链羰基、硅烷基或烃基,具有 1 至 30 个原子的支链或环状烷基,融合取代的芳香环和融合未取代的芳香环组成的组;x 的比例在 0.6 至 0.8 之间,y 的比例在 0.2 至 0.4 之间。
