| titleOfInvention | PPV derivatives containing fluorene and electroluminescence device with improved luminescence property including the same |
| abstract | The present invention provides an organic electroluminescent device having a poly (p-phenylenevinylene) derivative including fluorene of the formula (I) and an organic film containing the compound of formula (1), which is provided between a pair of electrodes It is to.n n n (I)n n n Wherein A, B, and C are each independently hydrogen or excluding hydrogen, or ego,n n n R 1 and R 2 each independently represent an alkyl group having 1 to 20 carbon atoms such as hydrogen, a phenyl group, a phenyl group substituted with an alkyl group having 1 to 20 carbon atoms, an alkoxy phenyl group having 1 to 20 carbon atoms, an ethylhexyl group, an octyl group, and the like. , Selected from the group consisting of ω-methoxypolyethylene oxide having 3 to 21 carbon atoms,n n n Ar is hydrogen, a phenyl group, a phenyl group substituted with an alkyl group having 1 to 20 carbon atoms, an alkoxy phenyl group having 1 to 20 carbon atoms, a substituted or unsubstituted naphthalene, a substituted or unsubstituted diphenylanthracene, a substituted or unsubstituted Substituted phenanthrene, substituted or unsubstituted indene, substituted or unsubstituted acenaphthene, substituted or unsubstituted carbazole, substituted or unsubstituted thiophene, substituted or unsubstituted oxazole, substituted or Unsubstituted benzothiophene, an aryl group, an alkyl group having 1 to 20 carbon atoms,n n n n is an integer from 10 to 10,000.n n n The organic electroluminescent device according to the present invention improves the luminous efficiency and improves the stability of the device by solving the problem of deterioration due to the driving heat generated when driving the device and the deterioration of the light emission characteristics due to the low purity of the material for forming the organic film. . As a result, luminous efficiency is improved. |
