Abstract

The present invention discloses a method for the intercalation of a chromophore within channels of a zeolite L crystal. The intercalated chromophores exhibit J type aggregation of the chromophores within the channels of the zeolite L crystals. The invention discloses method parameters which lead to the J type aggregation of the chromophores within the channels of the zeolite L crystals. The J type aggregation of the chromophores affords unique florescent properties rendering the intercalated zeolite L crystals as a material for use in novel optoelectronic devices.
