Paragraph 0297-0300, (2021/06/23)
The invention discloses a transition metal complex, a polymer, a mixture, a composition and an organic electronic device. According to the transition metal complex, due to the fact that the metal organic complex contains a ketone group and has excellent electron transmission capacity, the compound contains an arylamine group and also has excellent hole transmission capacity, and the transition metal complex has a stable six-membered ring structure, when the transition metal complex serves as a light-emitting layer doping material and is applied to an organic electronic device, especially an OLED, the light-emitting efficiency of the device can be improved, and the service life of the device can be prolonged.

A waste biomass, sodium lignosulfonate, was treated with sodium 2-formylbenzenesulfonate, and the phenylaldehyde condensation product was then used as a robust supporting material to immobilize a copper species. The so-obtained catalyst was characterized by many physicochemical methods including FTIR, EA, FSEM, FTEM, XPS, and TG. This catalyst exhibited excellent catalytic activity in the synthesis of nitrogen-containing heterocycles such as tricyclic indoles bearing 3,4-fused seven-membered rings, 2-arylpyridines, aminonaphthalenes and 3-phenylisoquinolines. In addition, this catalyst showed to be recyclable and could be reused several times without significant loss in activity during the course of the reaction process.
