Popis:	Four different coil-rod-coil metallo-supramol. 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 photophys. and electrochem. properties of these novel Ru(II) ABA assemblies. The aq. 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.
