Abstract: Disclosed are electroluminescent devices that comprise organic layers that contain certain 2H-benzotriazole compounds. The 2H-benzotriazole compounds of blue-emitting, durable, organo-electroluminescent layers. The electroluminescent devices may be employed for full color display panels in for example mobile phones, televisions and personal computer screens.

Abstract: A process for the preparation of organic material comprising an organic substrate and at least one dielectric layer consisting of one or more oxides of a metal selected from groups 3 to 15 of the periodic table, which comprises the steps of: (a) suspending the organic material in an aqueous solution of fluorine scavenger; (b) adding an aqueous solution of one or more fluorine containing metal complexes which are the precursors of the desired metal oxide coating; and (c) subjecting said suspension to microwave radiation to deposit the metal oxide onto said organic material, wherein steps (b) and (c) can optionally be repeated using different fluorine containing metal complexes to produce one or more metal oxide layers. The substrate can be optionally dissolved with solvent to yield free metal oxide or mixed metal oxides that have a plane-parallel structure.

Abstract: This invention pertains to a novel process for preparing sterically hindered N-substituted alkyloxyamines from alkenes by the transition-metal-catalyzed reaction of a intermediate alkylborane with a sterically hindered nitroxyl radical.

Abstract: The present invention relates to novel ultraviolet light absorbers of the benzoxazinone, oxanilide, benzylidene malonate, quinazoline and benzotriazole classes. The invention also relates to polymer and photographic compositions stabilized against the deleterious effects of light induced degradation which comprise the novel ultraviolet light absorbers.

Abstract: An environmentally friendly process is described for the preparation of 4-acyl-amino-2,2,6,6-tetramethylpiperidine-N-oxyl by the carbonate-mediated hydrogen peroxide oxidation of 4-acylamino-2,2,6,6-tetramethylpiperidine. The reaction can also be run in the absence of any catalyst.
