Time- and space-resolved luminescence of a photonic dye -: Zeolite antenna

In a radiationless process, electronic excitation energy can be transported in the photonic antennae presented herein from the borders to the center of cylindrical zeolite L crystals (ca. 2 μ). These antennae are formed by supramolecular organization (see schematic representation) of a cationic and a neutral dye in the parallel channels of the crystal. The rectangles symbolize adsorption sites, for which the red ones are filled with red-emitting dyes and blue ones with blue-emitting dyes.
