| Abstract |
|
Although polymers based on inorganic elements are of growing interest, apart from the synthesis of poly(dimethylsiloxane) as "silly putty", easily implemented experiments on these materials are extremely rare. This laboratory experiment involves the synthesis of an unusual organometallic, ferrocene-containing monomer and the subsequent ring-opening polymerization (ROP) of this species to afford a high molecular weight organometallic polymer, a poly(ferrocenylsilane), which can be easily handled in air. The ROP reaction can be carried out using transition metal catalysis or alternatively, thermally. The experiment also includes a simple illustration of the electrochromic behavior of these interesting organometallic polymeric materials: the color of a film of the poly(ferrocenylsilane) changes reversibly from amber to blue and back to amber on oxidation and subsequent reduction.
