Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? , Recommanded Product: 3-Bromo-10H-phenothiazine, The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 3939-23-9, Name is 3-Bromo-10H-phenothiazine, molecular formula is C12H8BrNS. In a article£¬once mentioned of 3939-23-9
A fluorene derivative and its organic electroluminescent device (by machine translation)
The present invention provides a containing and wu derivatives and their organic electroluminescent device, which belongs to the technical field of organic photoelectric material. The derivatives of formula (I) as shown in the structure, in the invention of the fluorene derivative and has relatively large conjugated plane structure, thus can provide high electronic mobility; introducing electron deficient group dibenzofuran, dibenzothiophene, acridine, phenoxazine, phenothiazine such structure or the like, and is more favorable to accept electronic, make it have good transmission performance; the introduction of bridge connecting structure, on the one hand can increase the molecular weight of the compounds, the resulting material has a high glass transition temperature and can prevent crystallization of the, on the other hand make such derivatives in space three-dimensional structure is provided with a distorted, improve membranaceous forming. The compound as the main material in the luminescent layer is made of the use of the organic electroluminescent device, demonstrate the low driving voltage, advantages of high luminous efficiency, excellent performance of the organic light-emitting material.
