A complexometric procedure is described for the separation of Zr, Th, and Ti from each other and from Sc and various lanthanides. Anal. determinations were made by titration of complexes formed with EDTA, diethylenetriaminepentaacetic acid, and triethylenetetraminehexaacetic acid and various complexon-type complex formers. Xylenol Orange was used as indicator. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2Quality Control of 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. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents. 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.Quality Control of 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl

Pyridine-Containing Electron-Transport Materials for Highly Efficient Blue Phosphorescent OLEDs with Ultralow Operating Voltage and Reduced Efficiency Roll-Off was written by Ye, Hua;Chen, Dongcheng;Liu, Ming;Su, Shi-Jian;Wang, Yi-Fan;Lo, Chang-Cheng;Lien, A.;Kido, Junji. And the article was included in Advanced Functional Materials in 2014.Product Details of 96761-85-2 This article mentions the following:

Pyridine-containing electron-transport materials are developed as an electron-transport layer for the FIrpic-based blue phosphorescent organic light-emitting diodes. Their energy levels can be tuned by the introduction of pyridine rings in the framework and on the periphery of the mols. Significantly reduced operating voltage is achieved without compromising external quantum efficiency by solely tuning the N atom orientations of those pyridine rings. Unprecedented low operating voltages of 2.61 and 3.03 V are realized at 1 and 100 cd m^-2, giving ever highest power efficiency values of 65.8 and 59.7 lm W^-1, resp. The operating voltages at 100 cd m^-2 can be further reduced to 2.70 V by using a host material with a small singlet-triplet exchange energy, and the threshold voltage for electroluminescence can even be 0.2 – 0.3 V lower than the theor. min. value of the photon energy divided by electron charge. Aside from the reduced operating voltage, a further reduced roll-off in efficiency is also achieved by the combination of an appropriate host material. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2Product Details of 96761-85-2).

Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Computed Properties of C24H15Br3
