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. 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.Safety of 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl

Multifunctional electron-transporting indolizine derivatives for highly efficient blue fluorescence, orange phosphorescence host and two-color based white OLEDs was written by Wan, Jing;Zheng, Cai-Jun;Fung, Man-Keung;Liu, Xiao-Ke;Lee, Chun-Sing;Zhang, Xiao-Hong. And the article was included in Journal of Materials Chemistry in 2012.Safety of 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl This article mentions the following:

Derivatives of 1-azaindolizine are 1st used as electron-transporting host materials for hybrid fluorescence/phosphorescence white organic LEDs (F/P-WOLED). Of the azaindolizine derivatives, a blue fluorescent material BPPI (3-(4,4′-biphenyl)-2-diphenyl-1-azaindolizine) has: (1) blue emission with high quantum yields, (2) good morphol. and thermal stabilities, (3) electron-transporting properties, and (4) a sufficiently high triplet energy level to act as a host for red or yellow-orange phosphorescent dopants. The multifunctional BPPI enables adaptation of several simplified device configurations. For example, a nondoped blue fluorescent device exhibits good performance with an external quantum efficiency of 3.16% and Commission Internationale de l’Eclairage coordinates of (0.15, 0.07). A high-performance orange phosphorescent device has a high current efficiency of 23.9 cd A-1. Using BPPI, a F/P-WOLED with a simplified structure, stable emissions and respectable performance (current and external quantum efficiencies of 17.8 cd A-1 and 10.7%, resp.) was demonstrated. In the experiment, the researchers used many compounds, for example, 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl (cas: 96761-85-2Safety of 3,3”-Dibromo-5′-(3-bromophenyl)-1,1′:3′,1”-terphenyl).
