Summary: | To provide a material for an organic photoelectric conversion element that selectively absorbs green light with a maximum absorption wavelength of 500 to 600 nm and has excellent heat resistance to process temperature when used in a photoelectric conversion unit, and an organic photoelectric conversion element that includes the material for the organic photoelectric conversion element and is driven by showing a clear light-dark ratio without causing destruction of the element even when a high voltage is applied.SOLUTION: There is provided a material for an organic photoelectric conversion element containing an organic compound represented by the following formula (1). (R1 to R8 in the formula (1) independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aromatic group, respectively. However, a case in which all R1 to R8 are hydrogen atoms is except).SELECTED DRAWING: Figure 1
