CHARGE-TRANSPORTING VARNISH |
摘要 |
A charge-transporting varnish which contains a charge-transporting substance containing fluorine atoms, a charge-transporting substance containing no fluorine atoms, a dopant substance composed of a heteropolyacid, and an organic solvent. The charge-transporting substance containing fluorine atoms is a polymer which is obtained by condensing a triaryl amine compound, an arylaldehyde compound containing fluorine atoms, a fluorene derivative having a carbonyl group and a carbazole derivative having an alkyl group or an alkyl group containing an ether structure in the N-position, and which has a weight average molecular weight of 1,000-200,000. The charge-transporting substance containing no fluorine atoms is an oligoaniline compound. A thin film formed from this charge-transporting varnish is capable of providing an organic EL element having excellent luminance characteristics and durability even in cases where the thin film is used as a single layer between a positive electrode and a light emitting layer in such a manner that the thin film is in contact with the positive electrode and the light emitting layer. |

1. A charge-transporting varnish comprising:
a charge-transporting substance containing a fluorine atom; a charge-transporting substance containing no fluorine atom; a dopant substance of heteropolyacid; and an organic solvent, wherein said charge-transporting substance containing the fluorine atom is a polymer having a weight-average molecular weight of 1,000 to 200,000 which is obtained by condensation from a triarylamine compound, arylaldehyde compound containing a fluorine atom, fluorene derivative having a carbonyl group, and carbazole derivative having at the N-position an alkyl group or an alkyl group having the ether structure, said charge-transporting substance containing no fluorine atom is an oligoaniline compound. |
