Hierarchical Self-Assembly of a Biomimetic Light-Harvesting Antenna Based on DNA G-Quadruplexes

A new modular approach to an artificial light‐harvesting antenna system is presented. The approach involves the hierarchical self‐assembly of porphyrin acceptor molecules to G‐quadruplexes tethered to coumarin donor moieties. A new organization: A new and versatile supramolecular approach to the ass...

Description
Summary:A new modular approach to an artificial light‐harvesting antenna system is presented. The approach involves the hierarchical self‐assembly of porphyrin acceptor molecules to G‐quadruplexes tethered to coumarin donor moieties. A new organization: A new and versatile supramolecular approach to the assembly of a functional artificial light‐harvesting system based on DNA G‐quadruplexes is presented (see figure). The key advantages of the G‐quadruplex‐based concept include its modular nature and the ease of assembly, which allow rapid structural variation and optimization.
