Özet:

 

Phthalocyanines (Pcs) are established sensitive materials   for chemical gas sensors due to their superb sensing characteristics and the   achievable manifold in their analyte interaction properties. Their sorption   properties are determined by the metal ion center and substituents attached   to the periphery of the ring system. Similarly, vic-dioximes can be modified in   their sorption properties and employed as sensitive materials. In this work,   a nickel Pc and various vic-dioximes functionalized with the same   hexafluoroisopropanol moiety are assessed and compared in their gas-sensing   properties using the quartz crystal microbalance for the first time. This   specific substituent is selected for its hydrogen bond acidity for strong   interactions with analytes having corresponding sites. The synthesis and   characterization of the new compounds are described. Sensor results are   presented for ten selected organic compounds and the chemical warfare agent   simulant dimethyl methylphosphonate (DMMP). Both compound classes exhibit   good sensing performance but were found to exhibit very diverging analyte   preferences, as preferential sorption of either amines or polar compounds   was observed depending on the molecule type. Thus, by applying the same   substituent to different base molecules, sensitive compounds with very   distinct sensing properties can be realized.
