Reversible Switching between Linear and Ring Poly(EO)s Bearing Iron Tetraphenylporphyrin Ends Triggered by Solvent, pH, or Redox Stimuli

Autor: Michel Schappacher, Alain Deffieux

Publikováno v: Macromolecules. 44:4503-4510

The action of various external stimuli on telechelic poly(ethylene oxide) bearing iron(III) tetraphenylporphyrin chloride or iron(II) tetraphenylporphyrin derivatives at their ends has been investigated in organic and water media. Fully reversible ch

Molecular Containers Based on Amphiphilic PS-b-PMVE Dendrigraft Copolymers: Topology, Organization, and Aqueous Solution Properties

Autor: Alain Deffieux, Michel Schappacher, Christelle Lefebvre, Jean-Luc Putaux

Publikováno v: Journal of the American Chemical Society. 127:2990-2998

The synthesis, characteristics, and properties of amphipatic, water-soluble dendrigrafts, with a polystyrene core and polystyrene-b-poly(methyl vinyl ether) (PS-b-PMVE) diblock as external branches, are described. The dendrigrafts are observed by AFM

Publikováno v: Polymer. 45:1833-1843

This work deals with the study of comb-like vs. arborescent grafted copolymers made of poly(chloroethyl vinyl ether)-g-polystyrene (PCEVE-g-PS). We describe how the molecular architecture of the branched polymers affects their nanoscale organization
