《Leaping across the visible range: near-infrared-to-violet photon upconversion employing a silyl-substituted anthracene》 was written by Haruki, Rena; Sasaki, Yoichi; Masutani, Kouta; Yanai, Nobuhiro; Kimizuka, Nobuo. Application In Synthesis of 9,10-Dibromoanthracene And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020. The article conveys some information:
Upconverting near-IR (NIR) light (λ > 700 nm) to violet light (λ < 450 nm) based on triplet-triplet annihilation (TTA) is achieved for the first time by developing a silyl-substituted anthracene violet emitter and its sensitization by an osmium complex showing a singlet-to-triplet (S-T) absorption in the NIR range. In the experimental materials used by the author, we found 9,10-Dibromoanthracene(cas: 523-27-3Application In Synthesis 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%.Application In Synthesis of 9,10-Dibromoanthracene
