Abstract: To provide an organic photoelectronic element excellent in light emitting characteristics and long-term reliability. The organic photoelectronic element comprises a substrate, an anode provided on the substrate, a cathode facing the anode, a light emitting layer disposed between the anode and the cathode, a hole transport layer disposed between the light emitting layer and the anode, and an electron blocking layer provided in contact with the light emitting layer and the hole transport layer between the light emitting layer and the hole transport layer, wherein the hole transport layer contains a fluorinated polymer and an organic semiconductor material, and has a refractive index in the wavelength range of from 450 nm to 800 nm, of at most 1.60, the hole transport layer and the electron blocking layer are made of different materials from each other, and the LUMO energy level of the electron blocking layer is higher than the LUMO energy level of the light emitting layer and the LUMO energy level of the hole transfer layer.

Abstract: A near infrared absorbing dye includes a croconium-based compound shown in formula (AI). In formula (AI), ring Z is either an optionally substituted 6-membered ring including no heteroatom or an optionally substituted 5-membered ring including 0 to 3 heteroatoms in the ring, R1 and R2, R2 and R3, and R1 and a carbon atom or heteroatom as a part of ring Z may be linked to each other to respectively form a heteroring A, a heteroring B, and a heteroring C together with a nitrogen atom.

Abstract: A near-infrared absorbing dye includes a compound represented by formula (A). Each of R11 to R14 is independently a hydrogen atom, a halogen atom, a hydroxyl group, or an alkyl, aryl or alaryl group. Each of pairs R11 and R12, R12 and R13, and R13 and R14 may combine with one another to form a monocyclic ring or a polycyclic ring in which from 2 to 4 rings are fused. Each of R15 and R16 is independently an alkyl or alaryl group. R15 and R16 may combine with one another to form a cyclohetero ring having from 5 to 10 members together with the nitrogen atom.
