Disclosed is a multilayer electroluminescent device comprising a cathode, an anode, a light emitting layer (LEL) and a layer disposed between the cathode and anode containing a naphthalene compound represented by formula (1):
1
wherein
m is 0, 1 or 2;
each R
a
is an independently selected substituent and each n is independently 0 to 3;
each Ar
a
is an independently selected aromatic group; and
each Ar
b
is an independently selected carbocyclic aromatic group;
provided that two ring substituents may join to form a ring.
The device provides a desired high luminance.
本发明公开了一种多层电致发光装置,包括阴极、阳极、发光层(LEL)和位于阴极和阳极之间的层,该层包含由式(1)表示的萘化合物:
其中m为0、1或2;每个R是独立选择的取代基,每个n独立为0至3;每个A是独立选择的芳香族基;每个Arb是独立选择的环状芳香族基;前提是两个环取代基可以结合形成环。该装置提供所需的高亮度。
