Abstract

A nitrogen-containing heterocyclic compound is represented by Formula (I): wherein R 1 represents a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted alkoxy group having 1 to 20 carbon atoms; A represents a heterocyclic residue that contains at least one nitrogen atom and forms a six-membered aromatic heterocyclic ring; and n represents an integer of from 1 to 3.

Claims (7)

1. A nitrogen-containing heterocyclic compound represented by Formula (II):

wherein R 1 represents a hydrogen atom, an unsubstituted alkyl group having 1 to 20 carbon atoms, or a substituted or unsubstituted alkoxy group having 1 to 20 carbon atoms; and n represents an integer of from 1 to 3.

2. The nitrogen-containing heterocyclic compound according to claim 1 , wherein R 1 is a straight-chain alkyl group.

3. The nitrogen-containing heterocyclic compound according to claim 1 , wherein the alkoxy group represented by R 1 is a straight-chain alkoxy group.

4. The nitrogen-containing heterocyclic compound according to claim 1 , wherein the alkoxy group represented by R 1 is an unsubstituted alkoxy group.

5. The nitrogen-containing heterocyclic compound according to claim 1 , wherein the substituent R 1 is in 3- or 4-positions of the benzene ring, relative to the thiophene ring which is in 1-position.

6. The nitrogen-containing heterocyclic compound according to claim 1 , wherein in Formula (II), R 1 is an alkyl group having 1 to 12 carbon atoms.
