Reaping the benefit: A supramolecular light-harvesting antenna has been developed by encapsulating small amounts of a π-conjugated oligomer (molecular wire) within self-assembled gel-forming donor scaffold. The tapes oligo(p-phenylenevinylene)s facilitate fast exciton migration and funneling excitation energy to encapsulated molecular wire, thereby resulting in intense red emission (see picture).
