Description: 
Organic–inorganic nano-hybrids, synthesized by supersonic molecular beams of TiO2 clusters and copper-phthalocyanine (CuPc) molecules, have been used to develop gas-sensing devices. This approach allows tailoring the properties of the synthesized materials and the interface between clusters and organic molecules so that new functional materials with interesting sensing properties are obtained. Two-layer hybrid devices with different architectures have been realized on alumina substrates with gold interdigitated electrodes. The hybrid films show an increase in conductivity up to a factor 6 compared to the pure CuPc depending on the architecture used. The response in terms of changes in conductivity towards non-oxidizing (methanol) species has been tested at different working temperatures. The hybrids show much higher sensitivity and stability with respect to CuPc grown with the same technique and …
