Molecular wire encapsulated into π organogels:: Efficient supramolecular light-harvesting antennae with color-tunable emission

(Figure Presented) Reaping the benefit: A supramolecular light-harvesting antenna has been developed by encapsulating small amounts of a n-conjugated oligomer (molecular wire) within a self-assembled gel-forming donor scaffold. The supramolecular tapes of oligo(p-phenylenevinylene)s facilitate fast exciton migration and funneling of the excitation energy to the encapsulated molecular wire, thereby resulting in intense red emission (see picture). © 2007 Wiley-VCH Verlag GmbH & Co.
