On February 5, 2019, Xing, Qifeng; Li, Zhiyang; Liu, Shuyao; Ren, Xueyan published a patent.Recommanded Product: 160377-42-4 The title of the patent was 2,6,9,10-Tetrasubstituted anthracene compound, and its application in organic light-emitting device. And the patent contained the following:
The inventive organic light-emitting device comprises a substrate, an anode layer, a 2,6,9,10-tetrasubstituted anthracene compound-containing organic functional layer (I; where Ar1 is a substituted or unsubstituted nitrogen containing heteroaryl group; Ar3 is a substituted or unsubstituted Ph, naphthyl, or biphenyl group; Ar2 is a substituted or unsubstituted aryl or ring group; and R1 can be a hydrogen, alkyl, halogen, nitro, cyano, or aryl group) and a cathode layer. The organic functional layer comprises a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer. One 2,6,9,10-tetrasubstituted anthracene compound (A1: 2,2′-((2,6-diphenylanthracene-9,10-diyl)bis(4,1-phenylene))dipyridine) is prepared by (1) stirring 2,6-dibromoanthracene-9,10-dione, phenylboronic acid, potassium carbonate, Pd2(dba)3, toluene, ethanol, and water under protection of nitrogen gas, heating to 100°C, and reacting under reflux for 12 h to obtain intermediate M2; (2) adding 2-(4-bromophenyl)pyridine and THF in a reactor, stirring, cooling to (-90)-(-80)°C, dropwise adding Bu lithium in 30 min, adding the intermediate M2, and stirring at room temperature for 8 h to obtain intermediate M3; (3) adding acetic acid in a reactor, stirring, heating to 60°C, adding the intermediate M3, KI, and sodium dihydrogen phosphate, and reacting under reflux at 120°C for 5 h. The invention has good voltage, efficiency and long service life. The experimental process involved the reaction of 5-(4-Bromophenyl)pyrimidine(cas: 160377-42-4).Recommanded Product: 160377-42-4
