General information

Title of the Project: Synthesis and characterization of 4H-dithieno[3,2-b;2’,3’-d]pyrrole substituented arylene bisimides - new donor-acceptor molecular semiconductors for organic electronics

Project Acronym: OE

Area of the Project: organic semiconductors, organic electronic devices, spectro- and electrochemistry

Summary: In the field of organic electronics there exists a large demand for electrochemically active materials, allowing the construction of low cost and environmental-friendly devices. Such materials can be used in organic field effect transistors (OLEDs), organic light-emitting diodes (OLEDs), organic solar cells (OSCs) and sensors. Therefore, in recent years, much research attention has been paid to the preparation of new compounds with controlled optical properties (energy gap) and electron (the position of HOMO and LUMO levels). HOMO and LUMO levels of organic semiconductors and, by consequence, their optical and redox properties as well as their air stability in device operating conditions, can be precisely tuned by appropriate balance between electron accepting and electron donating groups present in the molecule (macromolecules). Using the building blocks concept a series of molecules consisting of a central electron accepting (arylene bisimide) unit and two peripheral electron donating (4H-dithieno[3,2-b;2’,3’-d]pyrrole (DTP)) units will be synthesized. In this project it is expected to synthesize and investigate the spectroscopic, electrochemical and electrical transport properties of a new class of organic semiconductors namely arylene bisimides N- or core-functionalized with 4H-dithieno[3,2-b;2’,3’-d]pyrrole(DTP) substituents (NBIDTP). The expected outcome of the project is the use NBIDTP materials in various organic electronic devices fabricated by solution processing methods. As a result the development of new, solution-processable organic electroactive materials should allow for changing technology of electronic components. They can be used in the methods herein simpler, cheaper and less energy consuming than in the case of silicon electronics. A new type of electronics will then be at our disposal to simplify our lives in many areas.

Funding source: Norwegian Financial Mechanism, Polish-Norwegian Research Programme, Small Grant Scheme 2012 which provides support for research projects implemented by women specializing in the area of technical sciences.

Norwegian Financial Mechanism and the European Economic Area Financial Mechanism, i.e. EEA and Norway Grants, are a form of foreign aid granted by Norway, Iceland and Liechtenstein to new UE Member States. The funds are connected with the Polish accession to the European Union and the simultaneous accession to the European Economic Area (EU + Iceland, Liechtenstein, Norway and Switzerland). Donor countries benefit from access to the internal market of the European despite the fact that they are non-EU members. Currently, the second edition of the grants is being implemented, it covers the period 2009-2014. The previous edition covered the period 2004-2009.
