Li, Yan-Jun; Sasabe, Hisahiro; Su, Shi-Jian; Tanaka, Daisaku; Takeda, Takashi; Pu, Yong-Jin; Kido, Junji published an article on February 5 ,2010. The article was titled 《Highly efficient green phosphorescent OLED based on pyridine-containing starburst electron-transporting materials》, and you may find the article in Chemistry Letters.SDS of cas: 29102-67-8 The information in the text is summarized as follows:
Starburst materials, 1,3,5-tris[3,5-bis(pyrid-4-yl)phenyl]benzene (1a) and 1,3,5-tris[3,5-bis(pyrid-3-yl)phenyl]benzene (1b) were designed and synthesized. By using fac-tris(2-phenylpyridyl)iridium(III) [Ir(ppy)3] as a green emitter and 1 as an electron-transporting material, a green organic LED (OLED) was fabricated. The OLED exhibited a maximum power efficiency (PE) of 96 lm W-1 with an external quantum efficiency (EQE) of 23% at 2.1 cd m-2, and a PE of 75 lm W-1 with an EQE of 23% at 100 cd m-2. In addition to this study using 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl, there are many other studies that have used 3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8SDS of cas: 29102-67-8) was used in this study.
3,3”,5,5”-Tetrabromo-5′-(3,5-dibromophenyl)-1,1′:3′,1”-terphenyl(cas: 29102-67-8) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals.SDS of cas: 29102-67-8 The most pervasive is the naturally produced bromomethane.
