Organizing Supramolecular Functional Dye–Zeolite Crystals

Unidirectional antennas: Dyes in the open channels of the robust monolayers of zeolite L crystals on a glass substrate create a hierarchical order (see picture). Coupling the dye-loaded monolayers to an external acceptor or donor stopcock dye at the channel ends enables electronic excitation energy to be trapped from donor molecules inside the crystal or to inject it to an acceptor inside the channels.
