Photoelectric conversion film, photoelectric conversion element and electronic device

A photoelectric conversion element comprising:

• a photoelectric conversion film;
• a pair of electrodes that are disposed at both sides of the photoelectric conversion film, which is interposed therebetween;
• and
• a hole blocking layer disposed between the photoelectric conversion film and one of the electrodes,
• wherein a difference between an ionization potential of the hole blocking layer and a work function of the one of the electrodes is greater than or equal to 2.3 eV,
• wherein the hole blocking layer includes a compound represented by General formula (5):
• wherein in General formula (5), R50 is selected from the group consisting of hydrogen, a halogen, a hydroxy group, an alkoxy group, a cyano group, a nitro group, a silylalkyl group, a silylalkoxy group, an arylsilyl group, a thioalkyl group, a thioaryl group, a sulfonyl group, an arylsulfonyl group, an alkylsulfonyl group, an amino group, an alkylamino group, an arylamino group, an acyl group, an acylamino group, an acyloxy group, a carboxy group, a carboxamido group, a carboalkoxy group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heteroaryl group, and
• wherein Ar5 to Ar8 each represent the substituted or unsubstituted heteroaryl group.
