Fast progress in the development of new organic semiconducting materials for organic field effect transistors (OFETs) is associated with various annelated compounds among which fused phenylene-thiophene (benzothieno[3,2-b]benzothiophene (BTBT) derivatives) and thienothiophene-based (tetrathienoacene (TTA) derivatives) molecules have been widely investigated and shown to be promising. [1] Recently, new organic semiconductors, based on various octyl-substituted TTA derivatives were obtained [1,2]. Organosilicon dimer based on ВТВТ [3] was obtained to form a monolayer thin film with excellent electrical performance. Polymers based on annelated structures are poorly studied though seem to be very promising in printing/flexible electronics for OLED, OFET and solar cell perfomances. In this work we obtained a range of new linear polymers based on BTBT and TTA derivatives with an increased ability to self-assemble due to intra- and intermolecular interactions, as well as high flexibility due to alkyl spacers.
