Metal-organic frameworks (MOFs) are highly porous materials made from metallic ion clusters connected by organic linker molecules. The choice of these building blocks strongly affects the physical and chemical properties like pore size and adsorption behaviour. It has been shown that bringing networks of functionalized carbon nanotubes (CNTs) into a MOF synthesis can lead to a conducting, intergrown hybrid material with chemiresistive sensing properties.[1] We found a method to control UiO-66 MOF growth on individual CNTs. By local pretreatment with an electron beam we can define lines on which MOF growth is inhibited, leaving MOF-free spaces on a particular CNT giving a possible way to fabricate miniaturized MOF/CNT devices and exploring the interaction between these materials.
