Luminescent polymers having sterically twisted arylene repeat units are provided, which are particularly suited as electroluminescent polymers. Monomers necessary for the synthesis of the sterically twisted polyarylene are provided, as are electroluminescent device utilizing these polymers.

High bandgap arylene polymers

Objects of the present invention are to provide a purification process that enables Pd and P to be removed effectively, and to provide an electroluminescent material and an electroluminescent device obtained by employing the process. The present invention relates to a process for purifying an electroluminescent material, the process involving treating, with an oxidizing agent and then with a column, an electroluminescent material that contains Pd and/or P as impurities so as to remove the Pd and/or P.

Purification process of electroluminescent material, electroluminescent material and electroluminescent device

Photoluminescent and electroluminescent compositions are provided which comprise a matrix comprising aromatic repeat units covalently coordinated to a phosphorescent or luminescent metal ion or metal ion complexes. Methods for producing such compositions, and the electroluminescent devices formed therefrom, are also disclosed.

Polymer matrix electroluminescent materials and devices

Diodes having p-type and n-type regions in contact, having at least one of either the p-type region or n-type region including a conjugated organic material doped with an immobile dopant, conjugated organic materials for incorporation into such diodes, and methods of manufacturing such diodes and materials are provided.

Organic diodes and materials

High quantum yield luminescent monomers, oligomers, and polymers, comprising benzotriazole repeating units and derivatives thereof have been discovered and utilized in optical devices and components therefor, including electroluminescent devices, light emitting devices, photoluminescent devices, organic light emitting diodes (OLEDs), OLED displays, sensors, and the like. 

Luminescent compositions and their uses

Branched polyarylene polymers are provided comprising monovalent endcappers, divalent linear units, and polyvalent branching units. The composition of the polymers is controlled by adjusting the ratio of the three types of monomers.

Branched polyphenylene polymers

A new family of high temperature thermoset resins having high glass transition temperatures and enhanced hygrothermal stability that are synthesized using inexpensive starting materials in essentially a single step process. A trifunctional aromatic, wherein at least one of the three functional groups comprises a halogen and the balance thereof comprises OH groups and wherein said aromatic has electron withdrawing properties, is polymerized using an excess of a diol.
