The market of organic optoelectronic devices covering solar cells, light-emitting diodes, sensors, etc., is growing rapidly. The semiconducting capabilities of organic compounds are useful as their exploitation can reduce the industrial costs by substituting the expensive rare-earth materials and further expanding the advantages of the respective technologies. Organic chemicals not only tremendously increase the efficiency of commercial products but also contribute to sustainability aspects by minimizing pollution via the use of eco-friendly recyclable electronic materials and technologies. The selection of an appropriate stable organic core with a well-studied ?-conjugation is very important for the design of organic semiconductors. The application-driven characteristics are then tuned by the substitution of specific moieties in different positions, possibly facilitating charge transfer processes. The project idea is to thoroughly study the properties of new penta- and hexa- substituted benzene organic semiconducting derivatives and their potential for optoelectronics, attempt to optimize the applications by incorporation of nanoparticles and/or exploitation of lithography patterning techniques.. Based on recent developments in the field these compounds are expected to demonstrate prominent hole drift mobility values, and physical characteristics suitable for successful employment as functional electroactive materials for optoelectronic devices.
Project funding:
Research Council of Lithuania (RCL), Projects of Postdoctoral fellowships funded by the state budget of the Republic of Lithuania
Project results:
The overall goal is to provide alternatives to the well-studied commercial organic semiconductors utilized as hole transport materials and disclose their performance in the related optoelectronic demonstrator devices. The planned research would be beneficial for the scientists working in the field of organic optoelectronics as the new principles of the structure-property relationship of the penta- or hexa-phenylbenzenes will be discovered.
Period of project implementation: 2022-11-03 - 2024-11-02
