Orthogonally bifunctional fluorescent zeolite-L microcrystals

Microcrystals of zeolite L are functionalized with two different fluorescent dyes in a spatially resolved manner. The multiple functionalities and the selective derivatization of the channel entrances and of the coat of the zeolites result in interesting photophysical behavior as well as potential uses. The concept shown for the dyes can in principle be applied to any type of molecule.
