Abstract

The temperature dependences of the electrical conductivity and Seebeck coefficient for some polymers with pyrimidine repeating units are studied using thin films samples deposited from solutions. It was found that the polymers show semiconducting properties. The mechanism of electrical conduction in respective polymers is discussed. Some correlations between molecular structure of polymers and their semiconducting characteristics are established..

Keywords
