Surface-initiated atom transfer radical polymerization of electrochemically responsive cobalt-methacrylates

Balance of Hydrophilicity and Hydrophobicity of Stimuli-Responsive Metallopolymer-Decorated Organic Particles

“…19 Moreover, organic methacrylate-based nanoparticles were modified with a cobaltocene-containing polymer to achieve electrochemical-responsive material. 20 Functionalization with poly(2-(methacryloyloxy)ethyl ferrocene carboxylate) on polystyrene nanoparticles was accomplished by surface-initiated atom transfer radical polymerization (SI-ATRP). 21 This enabled a tailored design of the polymer chain length and controllable swelling behavior of the materials during the switching of ferrocene to ferrocenium.…”

“…For example, silica nanoparticles were modified with cobaltocene-containing polymers using surface-initiated reversible chain transfer polymerization, which were subsequently used in antimicrobial applications .

POSS-Containing Polymethacrylates on Cellulose-Based Substrates: Immobilization and Ceramic Formation

“…Especially the Greil group reported many interesting examples for the preparation of paper-derived ceramic materials in the last two decades and the authors pointed out that the morphology and porosity of the final hybrid materials can be tailored by the organic precursor architectures [37][38][39][40][41][42][43]. The presented technologies rely on the infiltration of the porous cellulose-based substrates, however, some recent advances show that functionalization by means of controlled radical polymerizations and the use of well-defined polymers can be advantageous with respect to the efficiency of polymer grafting and for maintaining the organic-templated morphology [29,[44][45][46][47][48].…”

Polycobaltoceniumylmethylene – A Water-Soluble Polyelectrolyte Prepared by Ring-Opening Transmetalation Polymerization

“…In general, metallocene-based polymers can be classified into main-chain and side-chain metallocene-containing polymers, whereby both types have been widely investigated and reported for a variety of applications ranging from biomedical applications to usage in catalysis, electronics, sensing or smart materials, and as precursors for nanostructured ceramics. − In contrast to the well-known ferrocene-based polymers, the corresponding isoelectronic, yet positively charged cobaltocenium-based polymers are underinvestigated . Nevertheless, cobaltocenium-based polymers have already demonstrated potential in different areas, like self-assembly, antimicrobial applications, and energy storage, as well as in mechanochemistry and bioconjugation, due to the valuable properties of the air stable cobaltocenium moiety featuring counterion-dependent solubility, high chemical stability, and robustness against oxidizing agents, as well as its antimicrobial properties. ,− The incorporation of cobaltocenium into the main-chain of a polymer gives rise to a cationic polyelectrolyte. However, the inertness of cobaltocenium salts and the convenient oxidation of the corresponding neutral 19-electron cobaltocene complicate the synthesis of cobaltocenium-based polyelectrolytes. , …”

“…The electrochemical behavior of 1-Cl was studied by cyclic voltametric measurements (CV) due to the cationic cobaltocenium center exhibiting redox-mediated switching capabilities (Figure ) and potential applications of such materials for switching the surface wettability or selective and redox-mediated interaction with ions or molecules, which will be investigated in the future. ,,,,,− …”
