Abstract
An organic electroluminescence device having one or more organic thin layers including a luminescent layer between an anode and a cathode, wherein at least one of the organic thin layers contains a compound or compounds selected from the group consisting of particular bianthryl, binaphthyl, trianthrylene and naphthylanthracene compounds, alone or in combination, the general formula of bianthryl compound being shown as follows:
Claims11
An organic electroluminescence device having one or more organic thin layers including a luminescent layer between an anode and a cathode, wherein at least one of the organic thin layers contains at least one of compounds selected from the group consisting of the compounds represented by general formulas I, II, III, and IV, alone or in combination;
- wherein R11 to R118 independently represent hydrogen, halogen, hydroxy, a substituted or unsubstituted amino, nitro, cyano, a substituted or unsubstituted alkyl, a substituted or unsubstituted alkenyl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted aromatic hydrocarbon, a substituted or unsubstituted aromatic heterocycle, a substituted or unsubstituted aralkyl, a substituted or unsubstituted aryloxy, a substituted or unsubstituted alkoxycarbonyl, or carboxyl groups;
- or two of R11 to R19 or two of R110 to R118 may be combined together to form a ring, although at least one of R11 to R118 is a diarylamino group represented by —NAr11Ar12 wherein Ar11 and Ar12 independently represent a substituted or unsubstituted aryl group having 6 to 20 carbon atoms;
- wherein R21 to R214 independently represent hydrogen, a halogen, hydroxy, a substituted or unsubstituted amino, nitro, cyano, a substituted or unsubstituted alkyl, a substituted or unsubstituted alkenyl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted aromatic hydrocarbon, a substituted or unsubstituted aromatic heterocycle, a substituted or unsubstituted aralkyl, a substituted or unsubstituted aryloxy, a substituted or unsubstituted alkoxycarbonyl, or carboxyl groups;
- or two of R21 to R27, or R28 to R214 may form a ring, although at least one of R21 to R214 is a diarylamino group represented by —NAr21Ar22 wherein Ar21 is a substituted aryl group having 6 to 20 carbon atoms which has at least one substituted or unsubstituted styryl substituent and Ar22 is a substituted or unsubstituted aryl group having 6 to 20 carbon atoms;
- wherein R31 to R326 independently represent hydrogen, a halogen, hydroxy, a substituted or unsubstituted amino, nitro, cyano, a substituted or unsubstituted alkyl, a substituted or unsubstituted alkenyl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted aromatic hydrocarbon, a substituted or unsubstituted aromatic heterocycle, a substituted or unsubstituted aralkyl, a substituted or unsubstituted aryloxy, a substituted or unsubstituted alkoxycarbonyl, or carboxyl groups;
- or two of R31 to R39, or two of R310 to R313 and two of R323 to R326, or two of R314 to R322 may form a ring, although at least one of R31 to R326 is a diarylamino group represented by —NAr31Ar32 wherein Ar31 and Ar32 are independently a substituted or unsubstituted aryl group having 6 to 20 carbon atoms;
- wherein R41 to R416 independently represent hydrogen, a halogen, hydroxy, a substituted or unsubstituted amino, nitro, cyano, a substituted or unsubstituted alkyl, a substituted or unsubstituted alkenyl, a substituted or unsubstituted cycloalkyl, a substituted or unsubstituted alkoxy, a substituted or unsubstituted aromatic hydrocarbon, a substituted or unsubstituted aromatic heterocycle, a substituted or unsubstituted aralkyl, a substituted or unsubstituted aryloxy, a substituted or unsubstituted alkoxycarbonyl, or carboxyl groups;
- or two of R41 to R49, or R410 to R416 may form a ring, although at least one of R41 to R416 is a diarylamino group represented by —NAr41Ar42 wherein Ar41 and Ar42 are independently a substituted or unsubstituted aryl group having 6 to 20 carbon atoms.
