1. An imaging device comprising:
a photoelectric conversion element which includes: a conductive thin layer; an organic photoelectric conversion layer including a compound represented by formula (I); and a transparent conductive thin layer, in this order, and further comprising: a region for accumulating an electric charge generated in the organic photoelectric conversion layer; and a signal read-out portion for reading out signals corresponding to electric charges accumulated in the region for accumulating an electric charge: wherein X represents O, S or N—R10, Rx and Ry each independently represents a hydrogen atom or a substituent W, wherein at least one of Rx and Ry is an electron-withdrawing group, and Rx and Ry may be connected to each other to form a ring, provided that Rx and Ry do not represent a cyano group at the same time, R7 to R10 each independently represents a hydrogen atom or a substituent W, wherein R8 and R9 may be connected to each other to form a ring, L represents a linking group comprising a conjugated bond, and D1 is a group represented by formula (VIII):
Formula (VIII); and wherein R21 to R24 each independently represents an alkyl group, and R22 and R23, or R21 and R22, may be connected to each other to form a ring, and wherein the substituent W represents a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxyl group, a nitro group, a carboxy group, an alkoxy group, an aryloxy group, a silyloxy group, a heterocyclic oxy group, an acyloxy group, a carbamoyloxy group, an alkoxycarbonyloxy group, an aryloxycarbonyloxy group, an amino group, an ammonio group, an acylamino group, an aminocarbonylamino group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfamoylamino group, an alkylsulfonylamino or arylsulfonylamino group, a mercapto group, an alkylthio group, an arylthio group, a heterocyclic thio group, a sulfamoyl group, a sulfo group, an alkylsulfinyl or arylsulfinyl group, an alkylsulfonyl or arylsulfonyl group, an acyl group, an aryloxycarbonyl group, an alkoxycarbonyl group, a carbamoyl group, an arylazo or heterocyclic azo group, an imido group, a phosphino group, a phosphinyl group, a phosphinyloxy group, a phosphinylamino group, a phosphono group, a silyl group, a hydrazino group or an ureido group. |
