We show here that non-network metallopolymers can possess intrinsic microporosity stemming from contortion introduced by metallocene building blocks. Metallopolymers constructed from ferrocenyl building blocks linked by phenyldiacetylene bridges are synthesized and possess BET surface areas up to 400 m2/g. As solubility imparted by pendant groups reduces porosity, copolymerization is used to simultaneously improve both accessible surface area and solubility. Spectroscopic analysis provides evidence that mixed valency between neighboring ferrocenyl units is supported in these polymers.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
