Title:
ELECTRON BUFFERING MATERIALS, ELECTRON TRANSPORT MATERIALS AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2017/073942
Kind Code:
A1
Abstract:
The present disclosure relates to an electron buffering material, and an organic electroluminescent device comprising a first electrode, a second electrode facing the first electrode, a light-emitting layer between the first electrode and the second electrode, and an electron transport zone and an electron buffering layer between the light-emitting layer and the second electrode. The organic electroluminescent device comprising the electron buffering material of the present disclosure has low driving voltage, excellent luminous efficiency, and long lifespan.
