Supramolecular host-guest systems as frameworks for excitation energy transfer.
The antenna behavior of rhodamine 6G and methylene blue loaded novel host supramolecular frameworks is investigated. The geometrical constraints of these supramolecular hosts allows the cationic dye molecules encapsulating within the parallel channels to form novel host-guest systems. The cationic dyes are close together that self-quenching of electronic excitation energy can occur. The excitation energy transfer occurs from rhodamine 6G as a donor (D) to methylene blue as an acceptor (A) within supramolecular systems filled with a mixture of both dyes.
