Replicating the Structure of a Crosslinked Polyferrocenylsilane Inverse Opal in the Form of a Magnetic Ceramic

Crosslinked polyferrocenylsilane inverse opals have been prepared by the thermal ring‐opening polymerization of spirocyclic [1]silaferrocenophanes confined within the interstitial void spaces of silica crystal colloidal templates. These organometallic polymer inverse opals were converted to magnetic ceramic replicas through pyrolysis at 900 °C in high yields. Crosslinked polyferrocenylsilane inverse opals have been prepared by the thermal ring …
