On May 15, 2009, Li, Shengbiao; Zhao, Ping; Huang, Yanqin; Li, Tingcheng; Tang, Chao; Zhu, Rui; Zhao, Lei; Fan, Quli; Huang, Shiqiang; Xu, Zushun; Huang, Wei published an article.SDS of cas: 146370-51-6 The title of the article was Poly-(p-phenylene vinylenes) with pendent 2,4-difluorophenyl and fluorenyl moieties: Synthesis, characterization, and device performance. And the article contained the following:
To improve efficiency, processability, and stability, three novel poly(p-phenylenevinylenes) (PPVs) derivatives (Pa, Pb, and Pc) with pendent 2,4-difluorophenyl and fluorenyl moieties were synthesized via Gilch reaction. Their structures were characterized by 1H NMR, 13C NMR, and ELEM. ANAL. Compared with those of PPV and MEH-PPV, the absolute quantum efficiencies of these polymers showed remarkable improvement (measured at 38.7, 37.2, and 20.3%, resp.), which can be attributed to the presence of twisted multiaryl segments and fluorine atoms. TGA revealed that the inflection temperatures of their thermal decomposition curves were above 400°. Double-layered electroluminescent devices with these polymers as light-emitting layers [ITO/PEDOT:PSS/Polymer/Ba/Al] showed peak emissions at 493/515, 503, and 600 nm and maximum luminance of 2700, 450, and 4700 cd/m2 for Pa, Pb, and Pc, resp., with onset voltages of ∼4 V. © 2009 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 47: 2500-2508, 2009. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).SDS of cas: 146370-51-6
