Abstract
Provided are a material that achieves higher sensitivity and higher resolution of a photoelectric conversion element for imaging, and a photoelectric conversion element for imaging using the above material. A material for a photoelectric conversion element for imaging, the material including a compound having a structure of the following general formula (1), wherein Ar1 to Ar3 represent an aromatic hydrocarbon group, an aromatic heterocyclic group, or a linked aromatic group in which two to six of these groups are linked, and at least two groups thereof have an aromatic ring structure represented by any of the following formulae (2) to (4). X represents O or S.
Claims11
A photoelectric conversion element for imaging, comprising a photoelectric conversion layer and an electron blocking layer between two electrodes, wherein at least one layer of the photoelectric conversion layer or the electron blocking layer contains a material for a photoelectric conversion element comprising a compound represented by the following formula (1);
- wherein Ar1 to Ar3 each independently represent a substituted or unsubstituted aromatic hydrocarbon group having 6 to 30 carbon atoms, a substituted or unsubstituted aromatic heterocyclic group having 3 to 30 carbon atoms, or a substituted or unsubstituted linked aromatic group in which two to six of the aromatic hydrocarbon group or the aromatic heterocyclic group are linked, at least two groups of Ar1 to Ar3 have an aromatic ring structure represented by any of the following formulae (2) to (4), and the aromatic ring structure optionally has a substituent,
- wherein X represents O or S.
