Abstract

Sticking together: The pore entrances of dye-loaded green or red zeolite L crystals can be site-specifically modified with either alkoxyamines or nitroxide radicals. Mild radical nitroxide exchange reactions of alkoxyamine-terminated “green” zeolite crystals with nitroxide-terminated “red” crystals leads to highly regular crystal chains that contain up to 15 covalently connected crystals with strictly alternating colors.
