Abstract

Disclosed is a novel compound represented by formula (1) below. In the formula, A represents an optionally substituted aromatic hydrocarbon ring or aromatic heterocyclic group, B represents a group including a chain of one to four pieces of one or more groups selected from groups represented by specific formulae (B-1) to (B-13) (such as —C═C— or —N═N—, specifically see the description), R1 to R3 each represent an optionally substituted hydrocarbon or hydrocarbonoxy group, at least one of R1 to R3 represents an optionally substituted hydrocarbonoxy group, R4 and R5 each represent an optionally substituted hydrocarbon group, R4 and R5 may be linked together to form a ring, and R4 and R5 may be each independently linked with A to form a ring

First claim

The invention claimed is:

1. A novel compound represented by formula (1):

wherein
A represents an optionally substituted aromatic hydrocarbon ring group or an optionally substituted aromatic heterocyclic group,
B represents a group comprising a chain of one to four pieces of one or more groups selected from groups represented by formulae (B-1) to (B-13) below,
R1, R2, and R3 each represent an optionally substituted hydrocarbon group or an optionally substituted hydrocarbonoxy group,
at least one of R1, R2, and R3 represents an optionally substituted hydrocarbonoxy group,
R4 and R5 each represent an optionally substituted hydrocarbon group,
R4 and R5 may be linked together to form a ring, and
R4 and R5 may be each independently linked with A to form a ring,

wherein
X represents S, O, or NR, wherein R represents an optionally substituted hydrocarbon group, and
any hydrogen atom may be replaced by a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, a cyano group, a nitro group, a hydroxyl group, a thiol group, an —NR7R8 group, or an optionally substituted aliphatic hydrocarbon group, wherein R7 and R8 each represent an optionally substituted hydrocarbon group,
wherein partial structure (3) shown below in formula (1) is partial structure (3-1) or (3-2) shown below,

wherein A, B, R4, and R5 have the same meanings as in formula (1),

wherein A, R4, and R5 have the same meanings as in formula (1).

2. The novel compound according to claim 1 , which satisfies at least one of the following conditions (i) to (iii):
(i) the group represented by B has at least one piece of group represented by any one of formulae (B-1) to (B-9) and (B-11) to (B-13);
(ii) R4 and R5 each represent an optionally substituted hydrocarbon group of 1 to 12 carbon atoms; and
(iii) at least one of R4 and R5 is linked with A to form a ring, and
wherein partial structure (3) shown below in formula (1) is partial structure (3-1) or (3-2) shown below,

wherein A, B, R4, and R5 have the same meanings as in formula (1),

wherein A, R4, and R5 have the same meanings as in formula (1).

3. The novel compound according to claim 1 , wherein R1, R2, and R3 in formula (1) each represent a linear or branched aliphatic hydrocarbonoxy group, and
wherein partial structure (3) shown below in formula (1) is partial structure (3-1) or (3-2) shown below,

wherein A, B, R4, and R5 have the same meanings as in formula (1),

wherein A, R4, and R5 have the same meanings as in formula (1).

4. A support material comprising a support and the novel compound according to claim 1 supported on the support.
