Patent ID: 8614438

Claim:
An organic photoelectric conversion device comprising: a first electrode; a second electrode opposing to the first electrode; and an organic material-containing photoelectric conversion layer provided between the first electrode and the second electrode, wherein the photoelectric conversion layer includes: a p-type organic material represented by formula (B) or (C), where (B) is where Z 11 is a ring containing at least two carbon atoms and represents a 5-membered ring, a 6-membered ring or a condensed ring containing at least one of a 5-membered ring and a 6-membered ring, each of L 11 , L 12 and L 13 independently represents an unsubstituted methine group or a substituted methine group, D 11 represents an arylene group or a hetero aromatic group containing —NR a (R b ) and each of R a and R b independently represents a hydrogen atom or a substituent, and n 1 represents an integer of 0 or more, and where (C) is where X represents O or N—R 10 , and R 10 represents a hydrogen atom or a substituent, each of R x and R y independently represents a hydrogen atom or a substituent, and at least one of them represents an electron-withdrawing group, and R x and R y may be connected to each other to form a ring; each R represents a bond, a hydrogen atom or a substituent, and at least of R's represents a bond (—), nr represents an integer of from 1 to 4, when nr is 2 or more, each R may be the same as or different from every other R, R's at the 2-position and 3-position, and R's at the 5-position and 6-position, may be connected to each other to form a ring; wherein an electron spin number of the photoelectric conversion layer is not more than 1.0×10 15 /cm 3 .
