1
represents a substituent. When there are two or more R

s in the same formula, they may be the same or different.)
(wherein, Y is —O—, —S— or —C(═O)—. Ar
1
represents an aryl group optionally having a substituent or a monovalent heterocyclic group optionally having a substituent, and there is no substituent connected to atoms of the ring of Ar
1
, the atoms being adjacent an atom of Ar
1
connected to a nitrogen atom in the formula. R
3
represents a substituent, and n represents an integer of from 0 to 3. When there are two or more R
2
s in the formula, they may be the same or different.).
一种共聚物,包含如下式(1)的重复单元和如下式(2)的重复单元:(其中,环A和环B各自独立地表示具有取代基的芳香环。X是-O-、-S-、-S(═O)-、-S(═O)2-、-Si(R1)2-Si(R1)2-、-Si(R1)2-、-、-B(R1)-、-P(R1)-、-P(═O)(R1)-、-O-C(R1)2-或-N═C(R1)-,R1表示一个取代基。当在同一式中有两个或更多的R1时,它们可以相同或不同。)(其中,Y是-O-、-S-或-C(═O)-。Ar1表示一个具有取代基的芳基团或一个具有取代基的单价杂环基团,并且没有取代基连接到Ar1的环上的原子,这些原子相邻于公式中连接到氮原子的Ar1的原子。R3表示一个取代基,n表示从0到3的整数。当在公式中有两个或更多的R2时,它们可以相同或不同。)
