摘要

1,2,4- second branched polymer compound according to the invention as shown in structural formula (I) (ortho and para-) p has a branching units (branched unit) from the coupling structure. The structure is characterized in that in combination with a linear unit (linear unit) ; ................. Formula (I) ; in the formula Ar ₁ and Ar ₂ is phenyl, biphenyl, fluorine, or an aromatic or heteroaromatic group such as thiophene and they include deuterium It will, or replaced by an aromatic or heteroaromatic ring not; R ₁ and R ₂ is H, or alkyl or alkoxy group; X is H or CN; And F is a functional end capping group.
