X-ray Structure of a Novel Tetrachloro[1.1]silaferrocenophane. Hydrolysis−Polycondensation of Poly(ferrocenyldichlorosilane). Electrochemical Studies

The thermal ring-opening polymerization of 1,1‘ferrocenediyldichlorosilane (m1) led to the expected poly(ferrocenyldichlorosilane) (p1) and the new dimer d1. The molecular structure of d1 was established by X-ray crystallography, and the electrochemical behavior was indicative of an electronic interaction between the ferrocene units. The hydrolytic sol−gel polycondensation of p1 led to a material in which the polymer chain was preserved during the process, as shown by the cyclic voltammetry study.
