Abstract

Conjugated inorganic/organic hybrid polymers, poly(phenylene vinylene ferrocenyl vinylene), was prepared by condensation polymerization of bisphosphonate reagent and ferrocenedialdehyde. Conjugated polymers having long alkyl side chains is very soluble in various organic solvents and thin polymer films can be easily produced by spin-coating technique. UV-Vis., NMR, cyclicvoltammetry, and GPC analysis were used to characterize the properties of conjugated polymers, and the averaged molecular weight was in the range of 7,000~25,000 (vs. PS standard). Electrical conductivity measurement of this processible conjugated polymer either in powder or in thin solid film showed very low conductivity probably due to the slow chain-to-chain hopping process. Third order nonlinear optical property of the conjugated polymers was measured as high as ϰ(3) = 1.24×10−8 esu in spin-coated thin film.
