NO(X) SENSITIVITY OF MONOMERIC AND POLYMERIC N-MACROCYCLIC COMPOUNDS

Thin films of a series of monomeric and polymeric metal phthalocyanine s with different center atoms (cobalt and copper) were prepared on int erdigitated capacitor or quartz microbalance devices. The coating was performed rom solution followed by subsequent evaporation of the solve nts. These devices have been tested for their use as NO2 resistance an d mass sensitive sensors. Particularly high sensitivity, reversibility and fast response times were obtained for nickel t-butyl phthalocyani ne (Ni-btPc) at room temperature and for poly[cyano(cobalt tetracarbox y phthalocyanine)] [(Co-taPcCN)n] at 100-degrees-C.
