摘要:
An organic electroluminescence device comprising an anode, an organic hole transport layer, an organic emission layer and a cathode layered in this order on a substrate, or, optionally, comprising an additional electron transport layer between the organic emission layer and the cathode, wherein the organic emission layer comprises a benzoxazinone derivative represented by formula (1), wherein R.sup.1 is a specific acyl group or sulfonyl group, and R.sup.2 and R.sup.3 are specific substituents.
摘要:
Laminar body comprising a substrate and, applied thereto on one or both sides, at least one layer containing an enamel, wherein the layer or layers containing an enamel contains/contain at least one phosphor.
摘要:
According to the process according to the invention, substantially fluorinated alkyl bromides, preferably perfluoroalkyl bromides, are prepared by reaction of substantially fluorinated alkyl iodides with organic bromine compounds in which the bromine atom is bound covalently to a carbon atom or a nitrogen atom.
