Patent ID: 8247687

Claim:
A photoelectric conversion element comprising a compound represented by the following Formula (1) between a pair of facing electrodes: wherein each of R 1 , R 2 and R 3 represents an aromatic hydrocarbon group or a heterocyclic group that may have a substituent; and each of at least two of R 1 , R 2 and R 3 is represented by the following Formula (2): wherein Ar represents an aromatic hydrocarbon group or a heterocyclic group that may have a substituent; n is an integer of 1-5; m is 0 or 1; each of Q 1 and Q 2 independently represents a hydrogen atom, a nitro group, a cyano group, a hydroxyl group, a carbonyl group, a thiol group, an alkyl group that may be substituted, an alkenyl group, an alkynyl group, an alkoxy group, a thioalkyl group, an amino group, an arylene group or a heterocyclic group; each of P 1 , P 2 and P 3 independently represents a hydrogen atom, a halogen atom, a nitro group, a cyano group, a hydroxyl group, a carbonyl group, a thiol group, an alkyl group that may be substituted, an alkenyl group that may be substituted, an alkynyl group, an alkoxy group that may be substituted, a thioalkyl group that may be substituted, an amino group that may be substituted, an aryl group that may be substituted or a heterocyclic group that may be substituted; at least one of P 1 , P 2 and P 3 represents an aromatic hydrocarbon group or a heterocyclic group substituted by an organic residue having an acidic group; R 1 , R 2 , R 3 , P 1 , P 2 , P 3 , Q 1 and Q 2 may form a cyclic structure directly, or via other bonded atoms; and a carbon-carbon double bond may be in any of a cis arrangement and a trans arrangement, and wherein the organic residue having the acidic group comprises an ethylene group substituted by a carboxylic acid group or a cyano group.
