Abstract
During the past few decades, processable organic semiconductors have been intensively studied due to their potential for a broad range of application in optoelectronics including e.g. organic light emitting diodes (OLEDs), organic photovoltaics (OPVs) and organic field effect transistors (FETs). Although remarkable progress has been made, the development of highly efficient and long-term stable optical and electrical devices is still a challenge. The milestones which stimulated the development of organic optoelectronics will be presented. After a brief introduction concerns the kinds of organic semiconductors together with their advantages and disadvantages, typical thiophene based materials will be discussed. The second part of this talk will be focused on unconventional compounds containing thiophene structures. Special emphasis will be put on compounds bearing imine linkages and/or aromatic imide rings. Thus, (poly) azomethines, (di) imides, azomethine naphthaldiimides, azines and others selected bithiophene derivatives reported in the literature also by our research group will be presented. The selected, mainly luminescence, electrochemical and photovoltaic properties of mentioned compounds making them an attractive for optoelectronics will be reported.
