Hydrogen‐bonded guanosine (G) dynamic supramolecular architectures exchange between different polymorphs such as G‐ribbons, G‐quartets and G‐quadruplexes. Oriented mesoporous silica can be used as a scaffolding matrix to orient and to stabilize lipophilic guanosine‐ribbons in confined conditions. The interface between the lipophilic G‐ribbons and the functionalized silica mesopores is based on reversible hydrophobic interactions. This contributes to the high level of adaptability and correlativity of the self‐organization of the supramolecular G‐ribbons and the oriented mesoporous silica systems. Biomimetic‐type hybrids, in which such structures are extremely stable and robust, can be generated by using this strategy.
