And the article was included in Advanced Materials (Weinheim, Germany) in 2008.SDS of cas: 96761-85-2 This article mentions the following:

Two pyridine-containing triphenylbenzene derivatives of 1,3,5-tri(m-pyrid-3-yl-phenyl)benzene (TmPyPB) and 1,3,5-tri(p-pyrid-3-yl-phenyl)benzene (TpPyPB) with high electron mobility and high triplet energy level are designed and synthesized. Highly efficient blue and green phosphorescent OLEDs are achieved by using TmPyPB and TpPyPB as an electron-transport layer, resp. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2SDS of cas: 96761-85-2).

3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.SDS of cas: 96761-85-2

Effect of Confined Spaces in the Catalytic Activity of 1D and 2D Heterogeneous Carbon-Based Catalysts for Synthesis of 1,3,5-Triarylbenzenes: RGO-SO₃H vs. MWCNTs-SO₃H was written by Golestanzadeh, Mohsen;Naeimi, Hossein. And the article was included in ChemistrySelect in 2019.Formula: C24H15Br3 This article mentions the following:

One hot debate between catalytic activities of sulfonated reduced graphene oxide (RGO-SO₃H), as the 2D heterogeneous carbon-based catalyst, and sulfonated multi-walled carbon nanotubes (MWCNTs-SO₃H), as the 1D heterogeneous carbon-based catalyst, was investigated in the synthesis of 1,3,5-triarylbenzenes under different conditions. This comparison study revealed that the 2D catalytic system was more efficient relative to the 1D catalyst in terms of yields of the target products, turnover frequency of the catalyst (TOF), and the reusability. The reasons of this observation such as sp. surface area, confinement spaces in 1D and 2D carbon-based catalysts, solvent accessible surface area, surface active sites, and the availability of supported functional groups on carbon nanostructures will discuss. Moreover, the application of synthesized compounds as a substrate was checked in carbon-carbon bond formation. Also, one of the synthesized compounds was produced using three approaches under metal and non-metal conditions. Notably, the recyclability of the two catalytic systems was checked. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2Formula: C24H15Br3).

3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Formula: C24H15Br3

Pyrimidine based hole-blocking materials with high triplet energy and glass transition temperature for blue phosphorescent OLEDs was written by Jang, Seokhoon;Han, Si Hyun;Lee, Jun Yeob;Lee, Youngu. And the article was included in Synthetic Metals in 2018.Name: 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl This article mentions the following:

New hole-blocking materials (HBMs), mPyrPPB and pPPyrPB, consisting of pyrimidine and phenylene segments for high-performance blue phosphorescent OLEDs were designed and synthesized. The thermal, electrochem., and optical properties of mPyrPPB and pPPyrPB were systemically studied. The T_g values of mPyrPPB and pPPyrPB were 118 and 137°, resp. The triplet energy and HOMO energy level of mPyrPPB were 2.77 eV and -6.86 eV, resp., indicating that it had sufficiently high triplet energy and deep HOMO energy level for the hole-blocking layer (HBL) in blue phosphorescent OLED devices. All the meta conjugation of mPyrPPB mol. structure effectively prevented π-electron delocalization and thus increased the triplet energy and electron transport property. MPyrPPB exhibited higher electron-transporting property than pPPyrPB because mPyrPPB possessed effective intermol. H bonds. When mPyrPPB was used as a HBM for a blue phosphorescent OLED device, external quantum efficiency (EQE), current efficiency (CE), and power efficiency (PE) values effectively increased to 16.4%, 36.7 cd/A, and 13.4 lm/W, resp. Compared to the reference device without HBM, EQE, CE, and PE increased by 38%, 35%, and 54%, resp., mainly due to the confinement of triplet excitons and holes and improved electron-transporting ability. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2Name: 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl).

3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Name: 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl
