Pelter, Andrew; Jones, D. Elfyn published an article in Perkin 1. The title of the article was 《The preparation and some properties of substituted phenylene-ethynylene and phenylenebuta-1,3-diynylene polymers》.Related Products of 74029-40-6 The author mentioned the following in the article:
Syntheses are described for the preparation of a variety of diynes which are converted to high mol. weight substituted arylenebuta-1,3-diynylene polymers by oxidative coupling and to high mol. weight substituted arylene-ethynylene polymers by Pd(II) catalyzed cross coupling reactions. The products tend to be insoluble in normal organic solvents. Doping with ferric chloride produces significant changes in conductivity but these are less than those produced on equivalently substituted thienylene-phenylene polymers.1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Related Products of 74029-40-6) was used in this study.
1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Although ethers resist hydrolysis, they are cleaved by hydrobromic acid and hydroiodic acid. Hydrogen chloride cleaves ethers only slowly. Related Products of 74029-40-6
