Metal-Organic Frameworks (MOFs) are porous crystalline materials with a characteristic large surface area. These materials were mainly investigated for applications as gas storage and separation and catalysis. The approach for using MOFs for sensing application was already done. MOFs show high potential for applications involving work function based gas sensing devices. In this work the Cu-BTC MOF was investigated as an aldehyde sensing material for work function readout based gas sensors at ambient conditions. The cross-sensitivity to humidity was proved. It is shown that Cu-BTC MOF sensing layers allow the distinguishing of molecules with similar chemical properties but different lengths.
