Semiconducting Organic Polymers Derived from Nitriles. Thermoelectric Power and Thermal Conductivity Measurements

Abstract

The thermal conductivities and thermoelectric powers of two previously reported polymeric organic semiconductive materials are reported. One system, thought to be a form of oxidized polyphthalocyanine, shows very complex behavior on heating in the presence of oxygen. The thermoelectric power is very sensitive to this treatment but the electrical resistivity, although changing slightly, is relatively insensitive. Two different oxygen—polymer effects, one reversible and one irreversible, appear to be superimposed in this system.
