Optically Functionalized Grid-Type Complexes by a Post-Assembly Strategy

Abstract Bisterpyridine‐based grid complexes can serve as supramolecular three‐dimensional scaffolds for the construction of larger molecular assemblies. Through functionalization of the ligand with azide groups, followed by self‐assembly and metal‐free Huisgen reactions, eight pyrene molecules can be attached to the grid structure in a single reaction step. The orientation and proximity provided by the scaffold allows for tuning the fluorescence properties of the dye molecules.
