The study of metallopolymers has blossomed into a mature field over the last few decades. Especially, polyferrocenylsilane (PFS) chemistry has taken a tremendous leap and continues to raise intense interest. Since the discovery of thermal ring-opening polymerization (ROP) of sila[1]ferrocenophanes, PFSs have been also accessed by anionic, cationic, transition-metal-catalyzed, and photolytic anionic ROP methodologies. A plethora of synthetic strategies have been devised, enabling access to a wide variety of copolymers, polyelectrolytes, and nanostructured materials. The distinctive physical properties and functions of many PFS-based polymers have been explored, leading to their apt exploitation in technical applications. Therefore, it is conceivable that PFS-related platforms might be indispensable nano-objects in the near future, as they stand on the verge of a new generation of sophisticated materials.

“…Ring-opening metathesis polymerization (ROMP) is a controlled polymerization tool to prepare polyferrocenes by the conversion of cyclic ferrocenyl olefin monomers under metathesis catalysts. − Although many such potential monomers have been reported, − relatively few have been used for polymerization. Most of these cyclic ferrocenyl monomers are synthesized by coupling two short alkyl substituents from each cyclopentadienyl ring, − which usually leads to polymers with poor solubility. ,, Ring-closing metathesis (RCM) of olefins is one of the most effective strategies to form cyclic compounds, − but to the best of our knowledge, polymerizable ferrocenyl precursors had not been prepared by ring-closing metathesis prior to our recent work . The effective preparation of polymerizable ferrocenyl monomers is challenging due to the often complex and ring size-dependent interplay of enthalpy and entropy in the ring-closing reaction .…”

Ring-Closing Metathesis and Ring-Opening Metathesis Polymerization toward Main-Chain Ferrocene-Containing Polymers

et al. 2018

We report the preparation of cyclic ferrocenyl olefins with various substituents and different ring sizes by ring-closing metathesis (RCM). These ferrocene-containing monomers were subject to ring-opening metathesis polymerization (ROMP), leading to main-chain ferrocene-containing homopolymers, random copolymers, and block copolymers. Depending on the substituents, ferrocenyl homopolymers are semicrystalline or amorphous with good solubility. A semicrystalline polymer was used in the crystallization-driven self-assembly (CDSA) of block copolymers to generate platelet nanostructures.
