Thin Films of a Cu-Phthalocyanine as resistive sensors for NO2 Detection

The role of porphyrins and phthalocyanines in thin films form in sensor application has been receiving an increasing interest in recent years and various synthetic methodologies can provide the opportunities to explore the influence of chem. modifications on their physico-chem. properties. In this context we report on the synthesis and film prepn. of a new bis-substituted Cu-phthalocyanine by using Langmuir-Blodgett deposition technique. Dynamic response characteristics of the elec. conductance to different NO2 concns. in dry air are presented
