Wu, Wei published the artcileSynthesis and light-emitting performance of MEH-PPV-type monomer 2,5-bis(4-bromo-2,5-dimethoxyphenylvinylene)-1-methoxy-4-(2-ethylhexyloxy)benzene, Synthetic Route of 146370-51-6, the publication is Hecheng Huaxue (2010), 18(2), 222-225, database is CAplus.
A method for the preparation of a green light-emitting monomer [i.e., bis[(4-bromo-2,5-dimethoxyphenyl)vinylene]-1-methoxy-4-[(2-ethylhexyl)oxy]benzene, 1,4-bis[2-(4-bromo-2,5-dimethoxyphenyl)ethenyl]-2-[(2-ethylhexyl)oxy]-5-methoxybenzene] was designed and the synthesis of the target compound was achieved (44.7% yield) by a Wittig-Horner reaction of 2,5-dimethoxy-4-bromobenzaldehyde with P,P‘-[[2-[(2-ethylhexyl)oxy]-5-methoxy-1,4-phenylene]bis(methylene)]bis[phosphonic acid] P,P,P‘,P‘-tetraethyl ester and the product thus obtained was confirmed by 1H-NMR, 13C-NMR, elemental anal. The light-emitting performance of that compound was also determined by UV-Vis and fluorescence anal. and the results showed that λmax of UV-Vis and fluorescence (FL) were 410 nm and 479 nm, 497 nm, resp. The title compound is a MEH-PPV-type monomer used for light-emitting diodes.
