- Abstract
Polymerization of two diphenylacetylenes having a ferrocenyl group at para or meta position, 1-[p-ferrocenylphenyl]-2-phenylacetylene (p-FcDPA) and 1-[m-ferrocenylphenyl]-2-phenyl-acetylene (m-FcDPA) and properties of the formed polymers were investigated. Both monomers polymerized with TaCl5-n-Bu4Sn catalyst in good yields to give reddish brown polymers. Poly(p-FcDPA) was insoluble in any solvents. On the other hand, poly(m-FcDPA) was soluble in CHCl3, THF, anisole, o-dichlorobenzene, and so on, and its weight-average molecular weight (Mw) was 53×104 and fairly high. A free-standing film of poly(m-FcDPA) could be easily fabricated by solution casting. The onset temperature of weight loss (T0) of poly(m-FcDPA) in air was ca. 310°C, indicating moderate thermal stability. Poly(m-FcDPA) was electrochemically active, and showed redox cycles based on the ferrocene moiety in cyclic voltammetry.
