The lipase-catalysed esterification of sugars with hemifluorinated acid derivatives is reported for the first time. A series of mannose modified derivatives having fluorinated chains with different length have been prepared accordingly in moderate yield. A preliminary evaluation of the surface active properties of these hemifluorinated mannose esters revealed their ability to reduce the surface tension of water much more efficiently than their aliphatic counterparts.

Graft copolymers have been prepared by one-step organometallic-mediated radical polymerization (OMRP) for the first time. Poly(ethylene glycol) acrylate (PEGA) was copolymerized with vinyl acetate (VAc) to yield well-defined P(PEGA-grad-VAc) gradient graft copolymers using bis(acetylacetonato)cobalt(II) as the control agent. The influence of experimental parameters such as the PEGA/VAc molar ratio, the nature of the initiator, and the temperature on the control of the copolymerization was discussed. The use of an excess of cobalt complex appeared as a key parameter to maintain a good level of control when higher contents of acrylate were used in the comonomer feed. The reactivity ratios were estimated and revealed that PEGA was added around 30 times faster than VAc, which gave access to a gradient P(PEGA-grad-VAc) copolymer or to a P(PEGA-grad-VAc)-b-PVAc diblock copolymer when the VAc polymerization was pursued after the full consumption of PEGA. The amphiphilic character of the copolymers makes them prone to self-assemble into micelles in water, as evidenced by dynamic light scattering. [less ▲]

This review focuses on an emerging class of controlled radical polymerization named Organometallic-Mediated Radical Polymerization (OMRP). The latter is based on the temporary deactivation of the growing radical species by a transition metal complex and the reversible formation of a carbon-metal covalent bond. Initially developed with cobalt complexes, OMRP has extended to several metals today. As highlighted here, the choice of the metal, the structure of ligands, temperature, and additives deeply affect the course of the polymerization and its mechanism. Macromolecular engineering opportunities offered by OMRP are also described, as well as practical applications sustained by the resulting polymer materials. [less ▲]

This communication will focuse on recent progress in the field of cobalt-mediated radical polymerization (CMRP). For example, the beneficial impact of cobalt complexes on the course of acrylate and vinyl chloride (VC) polymerizations will be discussed. The addition of conjugated unsaturated derivatives, like dienes, fullerenes and carbon nanotubes, onto (co)polymers preformed by CMRP has also been investigated. Similarities and differences between these radical addition processes will be presented as well as the potential applications of the resulting copolymers and carbon based materials for photodynamic therapy (PDT) and electromagnetic interferences (EMI) shielding.

Transition metal-assisted polymerization techniques have always played a crucial role in polymer synthesis. As an illustration, metallic compounds have deeply marked the field of living/controlled radical polymerization (L/CRP) which gives access to well-defined polymers under non drastic conditions. Indeed, atom transfer radical polymerization (ATRP) is one of the most successful methods to polymerize vinyl monomers in a controlled manner. Besides this very successful system, another metal-assisted CRP technique is emerging, i.e. organometallic-mediated radical polymerization (OMRP). In contrast to ATRP, OMRP involves the reversible formation of a covalent bond between a transition metal and the polymer chains, which strongly decreases the extent of termination reactions and leads to polymers with predictable molecular weights. This lecture aims to provide a comprehensive overview of the synthetic and mechanistic aspects of OMRP as well as major achievements and remaining challenges in this field. [less ▲]

Cobalt-Mediated Radical Polymerization (CMRP) is an efficient tool for polymerizing acrylates and vinyl esters. However, a challenge in CMRP remains in controlling the polymerization of both types of monomers with the same cobalt complex. Here, we show how Co(acac)2, efficient for unconjugated vinyl monomers, can also cope with acrylates. [less ▲]
