Organic electroluminescence element, lighting device and display device

摘要

Disclosed is an organic electroluminescent device having high external quantum efficiency and long emission life. Also disclosed are an illuminating device and a display, each comprising such an organic electroluminescent device. The organic electroluminescent device is characterized by comprising at least an anode and a cathode on a supporting substrate, while having at least one light-emitting layer between the anode and the cathode. The organic electroluminescent device is also characterized by containing a polymer which at least partially contains a compound A having a partial structure represented by the general formula (a) below and a reactive group, and is obtained by polymerizing the compound A through the reactive group. (In the formula, Ar1 and Ar2 respectively represent an aromatic ring.);

主权项

1. An organic electroluminescent element comprising:
a substrate having thereon an anode, a cathode, and at least one layer between the anode and the cathode, wherein the at least one layer comprises at least one emission layer, and the at least one layer comprises a compound A and a polymer prepared by polymerizing the compound A via a reactive group, provided that the compound A contains a partial structure represented by Formula (b) and the reactive group in the molecule: wherein, Ar1 represents a carboline ring or a dibenzofuran ring, and the reactive group is represented by any one of Formulas (3) to (5): wherein R represents a hydrogen atom or a methyl group; and Q represents a divalent linking group represented by any one of Formulas (c), (d), and (e) or any one of the plural combinations of Formulas (c), (d), and (e): wherein R1 and R2 each represent a hydrogen atom or a methyl group; and Cy represents a three membered or a four membered cyclic either group, provided that “n” is an interger of 0 to 2.
