“…Thermal transition data for various silicon pendant groups are listed in Tables 10 and 11. [172] Crystallization kinetics of PFMS suggest a 3D spherulitic growth and an instantaneous nucleation mechanism. [173] An insight to the possible conformations of PFMS chains in the solid state was obtained by single-crystal X-ray diffraction of well-defined oligomers and by molecularmechanics calculations.…”

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.

“…[60] Accordingly, ROP is a viable route for obtaining high-molecular-weight (M n % 10 4 -10 5 ) polymers from many of these compounds. [9,[57][58][59] ROP can be achieved by a variety of methods such as thermal, transitionmetal-catalyzed, anionic, and photolytic means. [52,61] Anionic and photolytic routes are "living" polymerizations that provide control over molecular weights and yield narrow molecular-weight distributions.…”

The structures, bonding, and ring-opening reactions of strained cyclic carbon-based molecules form a key component of standard textbooks. In contrast, the study of strained organometallic molecules containing transition metals is a much more recent development. A wealth of recent research has revealed fascinating nuances in terms of structure, bonding, and reactivity. Building on initial work on strained ferrocenophanes, a broad range of strained organometallic rings composed of a variety of different metals, pi-hydrocarbon ligands, and bridging elements has now been developed. Such strained species can potentially undergo ring-opening reactions to functionalize surfaces and ring-opening polymerization to form easily processed metallopolymers with properties determined by the presence of the metal and spacer. This Review summarizes the current state of knowledge on the preparation, structural characterization, electronic structure, and reactivity of strained organometallic rings with pi-hydrocarbon ligands and d-block metals.

“…Manners et al reported that PFDMS has the glasstransition temperature (T g ) of ϳ33°C and the T g of PFMPS is ϳ90°C, 13,20 which indicates that substituting a phenyl for a methyl in PFDMS decreased the conformational flexibility. On the other hand, the relative steric bulk of phenyl group may result in the fall of density of electroactive sites.…”

A series of poly(ferrocenylsilanes) (PFS) with different molecular weight have been prepared via the thermal ring-opening polymerization of the corresponding monomers. The electrochemical behavior of poly(ferrocenyldimethylsilane) (PFDMS) and poly(ferrocenylmethylphenylsilane) (PFMPS) in solutions were investigated by cyclic voltammetry (CV). It was found that PFS could be adsorbed and electrodeposited on the Pt electrode surface, and the electroactive multilayer films formed on the Pt electrode surface influenced the shape of the voltammogram. The redox potential varied with the molecular weight slightly, and ⌬E 1/2 became smaller with the increase in molecular weight.
