Among the controlled radical polymerization techniques, NMP offers an elegant way to prepare telechelic polystyrenes with augmented redoxactive centers directly from functionalized initiators. Such end groups are utilized to construct precisely controlled polymer architectures in a simple and modular fashion, e.g., <i>block</i>-copolymers with an internal redox cascade (Image 1) or <i>block</i>-copolymers featuring single interjacent photosensitzer unit (Image 2) - or both. Such hierarchical macromoelcular architectures can be tailored to mimick elementary processes of light-induced charge separation - combining excellent quantum effciencies (96%) with microsecond charge separation lifetime. In this regard, the progress in the divergent synthesis and simplified purification protocols is described to illustrate the feasability to design, prepare and utilzes such novel functional macromolecules.
