- Abstract:
- Four different coil-rod-coil metallo-supramolecular amphiphilic copolymers have been synthesized
via Ru(II) terpyridine complexation, using monoterpyridine end-functionalized poly(ethylene glycol) as hydrophilic
block A and different rigid-rod conjugated ditopic terpyridyl ligands as hydrophobic segment B. Those structures
are reminiscent of ABA triblock copolymers. Herein, we report for the first time the synthesis and characterization
as well as the photophysical and electrochemical properties of these novel Ru(II) ABA assemblies. The aqueous
self-assembly of these synthesized materials was studied by cryo-transmission electron microscopy and dynamic
light scattering, demonstrating a significant influence of the various middle segments B on the size of the obtained
micelles.
