New organo-soluble conjugated polyquinolines
Abstract
Polyquinolines are under discussion as n-type materials for organic field effect transistors, organic light-emitting diodes and organic solar cells together with other N-heterocycle-containing conjugated polymers. But most of these conjugated polyquinolines are not soluble in common organic solvents. Therefore, a new synthetic pathway is presented in this work leading to organo-soluble polyquinolines. The results of the synthesis and characterization of the obtained new organo-soluble polyquinolines are shown. The electrochemical reduction and oxidation behavior of these polymers is studied by cyclovoltammetric measurements. All studied polymers can be reversibly oxidized and reduced. The absorption and luminescence properties are investigated. Organic light-emitting diodes (OLEDs) are prepared from the new polyquinolines as an active single layer. The electroluminescence behavior and the characteristics of the OLEDs are discussed.
