- Abstract:
- A novel strategy to control the formation of amphiphilic brushes from metallo-supramolecular block
copolymers is described. The investigated copolymer consists of a polystyrene block linked to
a poly(ethylene oxide) one via a charged bis-terpyridine ruthenium(II) complex (PS-[Ru]-PEO). The
initial hexafluorophosphate counterions associated to the complex have been exchanged for
poly(styrenesulfonate) anions (PSS). In DMF, flexible amphiphilic brushes are observed in which PS-
[Ru]-PEO chains decorate the PSS main-chain. These structures have been further transferred into pure
water, resulting in the collapse of the PS chains into hydrophobic cores. Spherical or worm-like micelles
have been observed in water, depending on the length of the PSS chain.
