On March 8, 2007, Jin, Youngeup; Jee, Jaesung; Kim, Kwanghyun; Kim, Jinwoo; Song, Suhee; Park, Sung Heum; Lee, Kwanghee; Suh, Hongsuk published an article.SDS of cas: 146370-51-6 The title of the article was Synthesis and electroluminescent properties of copolymers based on PPV with fluoro groups in vinylene units. And the article contained the following:
Electroluminescent copolymers with fluoro groups on vinylene units, poly(2-ethylhexyloxy-5-methoxy-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (MEH-PPV-co-DMOS-PPDFV) and poly(2-dimethyloctylsilyl-p-phenylenevinylene-co-2-dimethyloctylsilyl-p-phenylenedifluorovinylene) (DMOS-PPV-co-DMOS-PPDFV), were synthesized by the Gilch polymerization route. The fluoro groups were introduced on vinylene units to increase the electron affinity of the copolymers. In both copolymers, the band gap increased with higher ratio of DMOS-PPDFV. As compared to the photoluminescence (PL) spectra in solution, the PL spectra in solid state and EL spectra of both copolymers showed red shift and broad peaks caused by aggregation. The LEDs fabricated using MEH-PPV-co-DMOS-PPDFVs emit light with maximum at around 538-577 nm. By adjusting the feed ratio of DMOS-PPDFV in the copolymer, the emission colors were tuned from orange yellow to green. The DMOS-PPV-co-DMOS-PPDFV showed maximum electroluminescence (EL) peaks at about 514-543 nm. The DMOS-PPV-co-DMOS-PPDFV with 1:9 feed ratio showed the highest luminescence efficiency of 1.31 lm/W. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).SDS of cas: 146370-51-6
