Organic electroluminescent cell, process for manufacturing the cell and its use.

摘要

Describes an organic electroluminescent cell (10) including an anode electrode (12), a cathode electrode (22), and a luminescent zone between said electrodes containing at least one organic luminescent agent and a binder having a breakdown field strength of at least about 10<5> volt/cm, wherein a hole-injecting zone comprising a layer (18) of a porphyrinic compound is situated between said luminescent zone and said anode electrode. Also relates to a process for manufacturing such cell, characterized by coating the anode electrode with layers constituting the luminescent zone and the hole-injecting zone by solvent coating and/or vapor deposition techniques and then applying the cathode electrode. Further relates to the use of the organic electroluminescent cell for generating light by subjecting said electroluminescent cell to a selected voltage source.
