Patent ID: 7189877

Claim:
An arylamine derivative represented by the general formula (1): wherein R 1 to R 4 each independently represents a hydrogen atom, a linear, branched or cyclic alkyl group or alkoxy group, an aryl group, an aryloxy group, a halogen atom, an amino group, or a group represented by the following general formula (2), (3) or (4); Ar 1 and Ar 2 each independently represents a substituted or unsubstituted aryl group or hetero-aromatic group, and Ar 1 and Ar 2 may form a nitrogen-containing heterocyclic ring together with the nitrogen atom to which Ar 1 and Ar 2 bond; and Ar 3 represents a substituted or unsubstituted arylene group: wherein Y represents a group represented by any one of the following general formulae (5a) to (5f); and W represents a hydrogen atom or a substituted or unsubstituted aryl group: wherein R 5 s' may be the same or different and each represents a hydrogen atom, a linear, branched or cyclic alkyl group or alkoxy group, an ester group, a hydroxyl group, a halogen atom, a cyano group, a nitro group, an amino group, an aryl group, or an aryloxy group; E represents —CR 6 — or a nitrogen atom; D represents any one of an oxygen atom, a nitrogen atom, or a sulfur atom; R 6 represents a hydrogen atom, a linear, branched or cyclic alkyl group, an aryl group, an amino group, a cyano group, a nitro group, a hydroxyl group, or a halogen atom; and l and m each represents an integer of from 0 to 4, satisfying the relation of (l+m)≦4: wherein R 7 s' may be the same or different and each represents a hydrogen atom, a linear, branched or cyclic alkyl group or alkoxy group, an ester group, a hydroxyl group, a halogen atom, a cyano group, a nitro group, an amino group, an aryl group, or an aryloxy group; E represents —CR 8 — or a nitrogen atom; R 8 represents a hydrogen atom, a linear, branched or cyclic alkyl group, an aryl group, an amino group, a cyano group, a nitro group, a hydroxyl group, or a halogen atom; D represents any one of an oxygen atom, a nitrogen atom, or a sulfur atom; and r and s each represents an integer of from 0 to 4, satisfying the relation of (r+s)≦4.
