Abstract
A polymer including: a polyaryl backbone; and an organic side-chain group including a partial structure represented by the following General Formula (I) or (II).
Claims6
A polymer comprising:
- a polyaryl backbone;
- and
- an organic side-chain group comprising a partial structure represented by the following General Formula (I) or (II):
- where in General Formula (I), one of X1 and Y1 represents an alkoxy group which may have a substituent, or an acyloxy group which may have a substituent, and the other represents a hydrogen atom;
- Q1 to Q6 each independently represent a hydrogen atom, a halogen atom, a monovalent organic group, or a bond to a carbon atom or a nitrogen atom in an adjacent aryl ring;
- and adjacent groups among Q1 to Q6 may be linked together to form a part of a ring or be annelated to an adjacent benzene ring,
- where in General Formula (II), one of X2 and Y2 represents an alkoxy group which may have a substituent, or an acyloxy group which may have a substituent, and the other represents a hydrogen atom;
- one of X3 and Y3 represents an alkoxy group which may have a substituent, or an acyloxy group which may have a substituent, and the other represents a hydrogen atom;
- Q1 to Q6 each independently represent a hydrogen atom, a halogen atom, a monovalent organic group, or a bond to a carbon atom or a nitrogen atom in an adjacent aryl ring;
- and adjacent groups among Q1 to Q6 may be linked together to form a part of a ring or be annelated to an adjacent benzene ring.
