A polymer according to the present invention comprises a repeating structure represented by the following formula (1), wherein L and X each independently have a configuration in which are linked a plurality of conjugation forming structures each conjugated by itself, and each have at least one thienylene structure as the conjugation forming structure:
wherein each X represents a monovalent organic group that may have a substituent, each L represents a divalent organic group that may have a substituent, and each T represents a trivalent organic group that may have a substituent, with the proviso that in the formula, the X's represent the same group, the L's represent the same group, and the T's represent the same group.
根据本发明的聚合物包括由下式(1)表示的重复结构,其中 L 和 X 各自独立地具有一种构型,在这种构型中,连接着多个共轭形成结构,每个结构本身都是共轭的,并且每个结构都有至少一个
噻吩结构作为共轭形成结构:
其中每个 X 代表一个可能具有取代基的一价有机基团,每个 L 代表一个可能具有取代基的二价有机基团,每个 T 代表一个可能具有取代基的三价有机基团,但在式中,X 代表相同的基团,L 代表相同的基团,T 代表相同的基团。
