PHOTOELECTRIC CONVERSION ELEMENT, METHOD FOR USING THE SAME, IMAGING DEVICE, PHOTOSENSOR, AND COMPOUND

摘要

An object of the present invention is to provide a photoelectric conversion element having a photoelectric conversion film which exhibits heat resistance, a high photoelectric conversion efficiency, a low level of dark currents, rapid response, and sensitivity characteristics to red and can be produced by a vapor deposition processing that is continuously performed under a high-temperature condition. The photoelectric conversion element of the present invention is a photoelectric conversion element in which a conductive film, a photoelectric conversion film containing a photoelectric conversion material, and a transparent conductive film are laminated on one another in this order, wherein the photoelectric conversion material includes a compound represented by Formula (1).;

1. A photoelectric conversion element in which a conductive film, a photoelectric conversion film containing a photoelectric conversion material, and a transparent conductive film are laminated on one another in this order,
wherein the photoelectric conversion material includes a compound represented by Formula (1). (In Formula (1), Z1 is a ring which contains at least two carbon atoms and may have a substituent, and represents a 5-membered ring, a 6-membered ring, or a condensed ring which contains at least one of 5-membered ring and 6-membered ring. Each of L1, L2, and L3 independently represents a substituted or unsubstituted methine group. n represents an integer equal to or greater than 0. Ar1 represents a substituted or unsubstituted divalent arylene group or a substituted or unsubstituted divalent heteroarylene group. Each of Ar2 and Ar3 independently represents a substituted or unsubstituted aryl group or a substituted or unsubstituted heteroaryl group. Ar1 and Ar2, Ar1 and Ar3, and Ar2 and Ar3 may respectively form a ring by being bonded to each other, and at least either Ar1 and Ar2 or Ar1 and Ar3 forms a ring by being bonded to each other. Ar1 and L1 may form a ring by being bonded to each other, and the ring may have a substituent. At least one of Z1, Ar1, Ar2, and Ar3 is substituted with a halogen group or a halogenated alkyl group.)
