Invention relates to a single step preparation of alkali metal quinolate of general formula 1 wherein M=Lithium, sodium or potassium; R═H, alkyl (C1-C6), alkoxy, aryl, aryloxy, amino, amido or halogen (Cl, F, Br, I) which is substituted or unsubstituted with direct reaction of metal with 8-hydroxyquinoline. Substituted 8-hydroxyquinoline optionally have at least one substituent selected from the group consisting of alkyl, alkoxy, aryl, aryloxy, amino, amido at 2, 5 or 7 position. Halogen substituted 8-hydroxyquinolates are also prepared from this method in the yield of 90-95% from polar solvents like acetonitrile. These complexes are useful as light emitting and electron injecting materials in organic electronic devices. Also the doping of these materials in electron transport materials improves their electron mobility.

Method for Producing (Electro) Luminescent, Photoactive or Electrically (Semi) Conducting Polymers

Номер: US20130065358A1

Автор: Matthias Rehahn, Serena Nickel, Stefan Immel, Thorsten Schwalm

Принадлежит: TECHNISCHE UNIVERSITAET DARMSTADT

The invention concerns the production of poly(arylene-vinylenes) and related polymers whose polymerization is triggered photochemically. For that purpose, the low molecular starting materials are firstly cooled to temperatures which are so low that in fact their activation into mostly chinoid intermediate stages (the “active” monomer) occurs; the thermally induced polymerization, however, either does not occur or barely takes place at all. The polymerization is instead triggered in a separate step by means of electromagnetic radiation of a suitable wavelength—either using the absorption behavior of the low-molecular starting compounds/the monomers, or mediated by means of photoinitiators and/or sensitizers. By way of example, with this method a display is suitable to be coated with poly(arylene-vinylenes). The monomer is hereby deposited. The polymer is subsequently produced in a photo-induced manner. The remaining monomer is washed out. The process takes place at low temperatures.
