摘要:
Disclosed is a charge-transporting compound represented by the formula (1) below which is composed of a polymer having a polymer main chain wherein fluorene derivatives are connected at the 9-position which fluorine derivatives are respectively substituted by an amino group having an aromatic ring or a heterocyclic ring. By using such a charge-transporting compound in the charge-transporting thin film, an organic EL device can be operated at a low voltage and is able to have a high luminance, long life while being free from defects.
摘要:
Using a charge transporting organic compound made of a polymer whose polymer main chain has a fluorene derivative, which is substituted with an amino group having an aromatic ring or heterocyclic ring, connected thereto at the 9 position thereof, e.g. a compound represented by the following formula (1), in a charge transporting thin film, the resulting organic EL element ensures low voltage drive, a high luminance, a very long life and no imperfections.
