Abstract: Carrier transport in newly synthesized 2,6-polyphenylquinolines containing an oxygen or phenylamine bridge group between phenylquinoline moieties and alkylated derivatives of carbazole or indolo[3,2-b]carbazole as an arylene radical has been studied. Both electron and hole transport is observed in films of all the polymers studied, with mobility on the order of 10$^{-6}$ cm$^2$ V$^{-1}$ s$^{-1}$, which increases on passing from an oxygen-to a phenylamine-type bridging group and from carbazole-to indolocarbazole-based derivatives. It is demonstrated that the conductivity and conduction type can be controlled by varying the type (oxygen or phenylamine) of bridging group between the phenylquinoline moieties or by the selection of an arylene radical.
