A branched compound including a core part, at least one side chain part bonded to the core part, and an end, wherein one repeating unit or two or more repeating units expressed by the following formula (1) repeat in the or each side chain part, with the proviso that in a repeating unit bonded to the core part, T is bonded to the core part, and in two or more contiguous repeating units, each L is bonded to the T, each L is formed of a plurality of conjugation-forming units linked together; each L includes at least one thienylene unit as the conjugation-forming unit; and at least two of the groups existing at the ends of Ls (the ends of the L in sides which are not bonded to T) are acceptor groups.
(In the formula, each L represents a divalent organic group which may have a substituent and the T represents a trivalent organic group which may have a substituent.)
一种分支化合物,包括一个核心部分,至少一个与核心部分结合的侧链部分和一个末端,在该化合物中,由下式(1)表示的一个重复单元或两个或更多重复单元在每个侧链部分中重复,条件是在与核心部分结合的重复单元中,T与核心部分结合,在两个或更多相邻的重复单元中,每个L与T结合,每个L由多个共轭形成单元连接在一起形成;每个L包括至少一个噻吩亚烯单元作为共轭形成单元;并且在L的末端(在未与T结合的侧链中的L的末端)存在的至少两个基团是受体基团。(在公式中,每个L代表可能具有取代基的二价有机基团,T代表可能具有取代基的三价有机基团。)
