Calix[4]arene-based Metal-organic Frameworks as Sensor Materials

Metal-organic frameworks (MOFs) are class of hybrid materials with interesting properties for applications like sorption or sensing. The functionality and size of the pores can be controlled by variation of the linker molecules. In combination with calix[4]arene-based linker molecules which show intrinsic porosity, gas molecules can be adsorbed more effectively. Furthermore highly selective sensor materials can be formed due to the high adsorption affinity of calix[4]arenes to nitrogen oxides and nitro aromatic compounds (NACs) like TNT or nitrobenzene. In this project the synthesis of MOFs with various functionalised calix[4]arene derivatives is investigated to create porous frameworks for sorption and especially for sensing applications for these compounds. Another application could be a drug and release system for the nerve stimulating NO molecules.
