-
Paragraph 0083-0086, (2021/09/15)
The invention belongs to the technical field of organic synthesis, and particularly relates to a phenanthrene compound as well as a preparation method and application thereof and an organic electroluminescent device. Compared with a device prepared from organic electroluminescent materials commonly used in the prior art, the device prepared from the phenanthrene 9 compounds has excellent comprehensive performance in starting voltage, current efficiency, service HOMO life LUMO and the like, and can meet the requirement and of the industrialization layer on the overall performance of the device. 3.
Process for producing a diarylamine
-
, (2008/06/13)
Described is a process for producing a diarylamine, which comprises subjecting an arylamine to condensation reaction in the co-presence of anhydrous aluminum chloride and anhydrous calcium chloride. The process permits the production of a diarylamine in a high yield at a normal pressure while terminating the reaction in a short time; and also permits the production, at a low cost, of a diarylamine having a high purity to be usable sufficiently as an intermediate for the production of a raw material for an electronic material.
