Abstract:
A polymer which is represented by a formula selected from the group consisting of formulae (I), (II), (III) and (IV): wherein R0 represents a hydrogen atom or alkyl group with up to 10 carbons; R is selected from the group consisting of a hydrogen atom, a linear alkyl group with up to 10 carbons, a branched alkyl group with up to 10 carbons, and an aromatic group with up to 10 carbons; A represents a repeating structure comprising at least one of the below repeating unit 1 and repeating unit 2; wherein R0 represents each independently a hydrogen atom or alkyl group with up to 10 carbons; p is an integer of 2 to 6; A and Aâ€² represents each independently a repeating structure comprising at least one of the below repeating unit 1 and repeating unit 2; wherein R0 represents a hydrogen atom or alkyl group with up to 10 carbons; A represents a repeating structure comprising at least one of the below repeating unit 1 and repeating unit 2; wherein A represents a repeating structure comprising at least one of the below repeating unit 1 and repeating unit 2; wherein Z is represented by a structure selected from the group consisting of structures (i), (ii) and (iii); and Zâ€² is represented by formula (0); wherein Q represents an alkylene group, with or without a hetero atom; R1 is selected from the group consisting of a hydrogen atom, a linear alkyl group with up to 10 carbons, a branched alkyl group with up to 10 carbons, and an aromatic group with up to 10 carbons; G is a group having a bridge of conjugated bond; and Eacpt is an electron acceptor group;wherein the structures (i), (ii) and (iii) are: wherein Q represents an alkylene group, with or without a hetero atom; Ra1, Ra2, Ra3, Ra4, Ra5, Ra6, Ra7, and Ra8 are independently selected from the group consisting of a hydrogen atom, a linear alkyl group with up to 10 carbons, a branched alkyl group with up to 10 carbons, and an aromatic group with up to 10 carbons; wherein Q represents an alkylene group, with or without a hetero atom; Rb1-Rb27 are each independently selected from the group consisting of a hydrogen atom, a linear alkyl group with up to 10 carbons, a branched alkyl group with up to 10 carbons, and an aromatic group with up to 10 carbons; wherein Q represents an alkylene group, with or without a hetero atom; Rc1-Rc14 are each independently selected from the group consisting of a hydrogen atom, a linear alkyl group with up to 10 carbons, a branched alkyl group with up to 10 carbons, and an aromatic group with up to 10 carbons.
