TLDR
In this article, a stable organic electroluminescent devices based on vapor-deposited Alq thin films have been achieved, which are derived from several factors including: (1) a multilayer thin-film structure with a CuPc stabilized hole-injection contact, (2) a hole-transport diamine layer using a naphthyl substituted benzidine derivative, and (3) an ac drive wave form.Abstract:
Highly stable organic electroluminescent devices based on vapor‐deposited Alq thin films have been achieved. The improvement in stability is derived from several factors including: (1) a multilayer thin‐film structure with a CuPc stabilized hole‐injection contact, (2) a hole‐transport diamine layer using a naphthyl‐substituted benzidine derivative, and (3) an ac drive wave form. These emissive devices have shown an operational half‐lifetime of about 4000 h from an initial luminance of 510 cd/m2.read more

Display device with metal-organic mixed layer anodes
TL;DR: In this article, an anode is composed of a mixture of a metal-organic mixed layer and an electron-accepting material within a single layer of the anode, and a multilayer configuration is proposed, where the buffer layer comprises an electron accepting material and optionally a hole transport material.

Hole injection enhancements of a CoPc and CoPc: NPB mixed layer in organic light-emitting devices
TL;DR: The hole injection enhancement in organic light-emitting devices with the insertion of a cobalt phthalocyanine (CoPc) hole injection layer (HIL) between the indium tin oxide (ITO) anode and the N,N-bis(1-naphthyl)-N,N′-diphenyl-1,1′-biphenymyl-4,4′ -diamine (NPB) hole transport layer (HTL) was demonstrated through current density-voltage-luminance measurements, in

Synthesis and characterization of new highly soluble and thermal-stable perylene–PPV copolymers containing triphenylamine moiety
TL;DR: In this paper, three new copolymers containing poly(p-phenylenevinylene) (PPV) and triphenylamine (TPA) moieties carrying N-(n-butyl)-N′-ethoxy-1,6,7,12-tetra-(4-tert,butylphenoxy)-3,4,9,10-perylenetetracarboxylic bisimide (PERY) pendant groups were successfully synthesized by Wittig condensation.
