Organic photoelectric conversion element, two-dimensional sensor, image sensor, and imaging apparatus

An organic photoelectric conversion element comprising:

• an anode;
• a cathode;
• and
• a photoelectric converter, which is arranged between the anode and the cathode,
• wherein the photoelectric converter includes at least a first organic compound layer, and
• wherein the first organic compound layer contains a compound represented by general formula [1]:
• wherein, in the formula [1]:
• Ar1 and Ar2 each represent an alkyl group having 1 to 8 carbon atoms, an aromatic hydrocarbon group having 6 to 18 carbon atoms, or a heteroaromatic ring group having 3 to 15 carbon atoms, Ar1 and Ar2 may each further have a substituent selected from a halogen atom, a cyano group, an alkyl group having 1 to 6 carbon atoms, a phenyl group, a tolyl group, a xylyl group, a mesityl group, and a cumenyl group, and when Ar1 and Ar2 each represent an aromatic hydrocarbon group having 6 to 18 carbon atoms or a heteroaromatic ring group having 3 to 15 carbon atoms, Ar1 and Ar2 may be bonded to each other via any one of a single bond, and a methylene group and an ethylene group each of which may have an alkyl group to form a ring structure;
• Ar3 represents a fused polycyclic aromatic hydrocarbon group formed by fusion of 4 or 5 six-membered rings, excluding an acene group and a 2,7-pyrene group, Ar3 may further have a fluorine atom, a cyano group, a methyl group, or a tert-butyl group, and when Ar2 represents an aromatic hydrocarbon group having 6 to 18 carbon atoms or a heteroaromatic ring group having 3 to 15 carbon atoms, Ar2 and Ar3 may be bonded to each other via any one of a single bond, and a methylene group and an ethylene group each of which may have an alkyl group to form a ring structure;
• and
• Q represents a substituent selected from a group of substituents represented by general formulae [2a] to [2e]:
• wherein, in the formulae [2a] to [2e], R1 to R27 each represents a substituent selected from a hydrogen atom, a fluorine atom, an alkyl group having 1 to 4 carbon atoms, or a cyano group, and * represents a bonding site with Ar3.
