Ring-Opening Polymerization of a Galla[1]ferrocenophane: A Gallium-Bridged Polyferrocene with Observable Tacticity

Abstract

A gallium-bridged polyferrocene was prepared via spontaneous ring-opening polymerization of a galla[1]ferrocenophane. This organometallic polymer is thermally robust and can be purified and handled under ambient conditions, making it an ideal candidate for incorporation into polymer based materials offering an alternative to existing polyferrocenes. The tBu group pointing toward the polymer backbone serves as a very sensitive NMR probe of the polymer stereochemistry.
