Quality Control of 3-IodophenolIn 2022 ,《Molecular engineering by σ-linkers enables delayed fluorescence emitters for high-efficiency sky-blue solution-processed OLEDs》 was published in Chemical Engineering Journal (Amsterdam, Netherlands). The article was written by Chen, Yanying; Li, Nengquan; Huang, Zhongyan; Xie, Guohua; Yang, Chuluo. The article contains the following contents:
Two novel thermally activated delayed fluorescence (TADF) emitters, Me2AcBO and F2AcBO, based on the 9,9-dimethylacridine donor and a rigid O-bridged cyclized B acceptor, were designed and synthesized for highly efficient blue solution-processed organic light-emitting diodes (OLEDs). Me2AcBO and F2AcBO feature a twin structure derived by coupling 2 individual TADF monomers through nonconjugated linkers. The 2 new emitters exhibit 3D mol. structures, excellent thermal/morphol. properties, high luminescence quantum yields >97%, and high reverse intersystem crossing rates ∼106 s-1, which greatly benefit the high device efficiency. Solution-processed sky-blue TADF OLEDs based on Me2AcBO and F2AcBO achieved the maximum external quantum efficiency of 11.0 and 10.9%, resp., with Commission Internationale de L’Eclairage (CIE) coordinates of (0.14, 0.25). Relatively low efficiency roll-offs of 33 and 34% at the luminance of 1000 cd/m2 were demonstrated for Me2AcBO and F2AcBO based devices, resp. This study presents a novel strategy to realize highly efficient sky-blue TADF emitters for solution-processed OLEDs. After reading the article, we found that the author used 3-Iodophenol(cas: 626-02-8Quality Control of 3-Iodophenol)
3-Iodophenol(cas: 626-02-8) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Quality Control of 3-Iodophenol Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.
