Kim, Seunghyun; Kang, Seokwoo; Parkit, Jongwook published an article in 2021. The article was titled 《Synthesis and electro-optical property of green fluorescent emitter based on anthracene core and optimized side groups》, and you may find the article in Journal of Nanoscience and Nanotechnology.Reference of 9,10-Dibromoanthracene The information in the text is summarized as follows:
New green emitter is designed and synthesized by selecting anthracene having high photoluminescence quantum yield (PLQY) and diphenylamine side group substituted Me and t-Bu group: N9, N10-bis(5-(tert-butyl)-2-methylphenyl)-N9, N10-bis(2,4-dimethylphenyl)anthracene-9,10-diamine (3Me-1Bu-TPADA). Photophys., electrochem., and electroluminescent (EL) properties of 3Me-1Bu-TPADA were investigated. The maximum photoluminescence (PL) emission wavelengths of 3Me-1Bu-TPADA in solution and in a film were 528 nm and 531 nm, resp. 3Me-1Bu-TPADA has excellent thermal properties with glass transition temperatures (Tg) of 110 °C, melting temperatures (Tm) of 217 °C of, and degradation temperature (Tg) of 330 °C. 3Me-1Bu-TPADA was used as an emitting layer in non-doped devices: ITO/2-TNATA (60 nm)/NPB (15 nm)/3Me-1Bu-TPADA (30 nm)/Alq3 (30 nm)/LiF (1 nm)/Al (200 nm). The 3Me-1Bu-TPADA device showed luminance efficiency of 6.05 cd/A, EQE of 2.68% at 10 mA/cm2. In the part of experimental materials, we found many familiar compounds, such as 9,10-Dibromoanthracene(cas: 523-27-3Reference of 9,10-Dibromoanthracene)
9,10-Dibromoanthracene(cas: 523-27-3) is synthesized by the bromination of anthracene. The bromination reaction is carried out at room temperature using carbon tetrachloride as a solvent. Using 80-85% anthracene as raw material, adding bromine to react for half an hour, the yield is 83-88%.Reference of 9,10-Dibromoanthracene
