Li, Lin; Zhang, Chun; Xu, Lei; Ye, Changqing; Chen, Shuoran; Wang, Xiaomei; Song, Yanlin published an article in 2021. The article was titled 《Luminescence Ratiometric Nanothermometry Regulated by Tailoring Annihilators of Triplet-Triplet Annihilation Upconversion Nanomicelles》, and you may find the article in Angewandte Chemie, International Edition.Quality Control of 9,10-Dibromoanthracene The information in the text is summarized as follows:
Triplet-triplet annihilation (TTA) upconversion is a special non-linear photophys. process that converts low-energy photons into high-energy photons based on sensitizer/annihilator pairs. Here, we constructed a novel luminescence ratiometric nanothermometer based on TTA upconversion nanomicelles by encapsulating sensitizer/annihilator mols. into a temperature-sensitive amphiphilic triblock polymer and obtained good linear relationships between the luminescence ratio (integrated intensity ratio of upconverted luminescence peak to the downshifted phosphorescence peak) and the temperature We also found chem. modification of annihilators would rule out the interference of the polymer concentration and stereochem. engineering of annihilators would readily regulate the thermal sensitivity. In addition to this study using 9,10-Dibromoanthracene, there are many other studies that have used 9,10-Dibromoanthracene(cas: 523-27-3Quality Control of 9,10-Dibromoanthracene) was used in this study.
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%.Quality Control of 9,10-Dibromoanthracene
