✦ Synopsis

The effect of NO,, NO, F,, BC13, BF3, NH,, H,S, SOz and HCI at low concentrations (< 1 ppm) m allc on the electrical conductivity of a number of metal phthalocyanmes has been investigated Vacuum sublimed films of Pb, Zn, Cu, Nl, Co and Fe phthalocyamne have been shown to be sensltlve to NO2 and F, but msensltlve to more weakly electrophlhc and electrophoblc gases Increasing sensltlvlty to NOz was observed as phthalocyanmes contammg progressively heavier metals were used Magnesium phthalocyanme was affected only by HCl The potential of these materials as gas sensors 1s dlscussed *Paper presented at the Third Internatlonal Conference on Sohd-State Sensors and Actuators (Transducers' 85), Phladelphla,
