Abstract
An organic electroluminescent device includes an anode, a cathode, and an organic layer having a light-emitting area and arranged between the anode and the cathode. The organic layer contains in at least a part thereof at least one aminostyrylnaphthalene compound represented by the following formula [I], [II] or [III]: wherein R1, R2, R11, R12, R23 and R24 are each a phenyl or naphthyl group, R3, R4, R13, R14, R25 and R26 are each an electron attracting group such as a cyano group, and R5, R15 and R27 are each a substituent group such as an alkyl group.
Claims15
An organic electroluminescent device comprising an anode, a cathode, and an organic layer arranged between said anode and said cathode, wherein at least a part of said organic layer comprises at least one aminostyrylnaphthalene compound represented by the following formula [A]:
- wherein:
- Ra and Rb may be the same or different and each independently represents a substituted or unsubstituted aryl group,
- Rc, Rd, Re, Rg, Rh and Ri may be the same or different, at least one of Rc, Rd, Re, Rg, Rh and Ri independently represents a hydrogen atom, a cyano group, a nitro group, a trifluoromethyl group or a halogen atom, and the remaining one or ones of Rc, Rd, Re, Rg, Rh and Ri, if any, are each a hydrogen atom, a cyano group, a nitro group, a trifluoromethyl group or a halogen atom, and
- Rf represents an alkyl selected from the group consisting of methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, t-butyl, and allyl, a substituted or unsubstituted alicyclic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxyl group, a substituted or unsubstituted alicyclic hydrocarbyloxy group or a substituted or unsubstituted aromatic hydrocarbyloxy group.
An aminostyrylnaphthalene compound represented by the following formula [A]:
- wherein:
- Ra and Rb may be the same or different and each independently represents a substituted or unsubstituted aryl group,
- Rc, Rd, Re, Rg, Rh and Ri may be the same or different, at least one of Rc, Rd, Re, Rg, Rh and Ri independently represents a hydrogen atom, a cyano group, a nitro group, a trifluoromethyl group or a halogen atom, and the remaining one or ones of Rc, Rd, Re, Rg, Rh and Ri, if any, are each a hydrogen atom, a cyano group, a nitro group, a trifluoromethyl group or a halogen atom, and
- Rf represents an alkyl selected from the grow, consisting of methyl, ethyl, n-propyl, i-propyl, n-butyl, i-butyl, t-butyl, and allyl, a substituted or unsubstituted alicyclic hydrocarbon group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxyl group, a substituted or unsubstituted alicyclic hydrocarbyloxy group or a substituted or unsubstituted aromatic hydrocarbyloxy group.
