Organic Charge Transfer Applications

Periodic Reporting for period 1 - OCTA (Organic Charge Transfer Applications)

Reporting period: 2018-01-01 to 2019-12-31

Organic molecules are everywhere, they are integral to life, from every living species to new technologies like organic electronics. Organic molecules can be made with infinite variety but what happens when they are excited by light is more important. Molecular shape and molecular interactions are important in their application but what happens to them once excited is more critical and defines the function of that molecular within a more complex system. One of very interesting phenomena in organic molecules is electron transfer (ET) to form stable Charge Transfer excited states (CT). We may observe CT state everywhere, from living tissue to organic solar cell or organic light emitting diode. It is believed that birds use CT states to navigate. It is therefore crucial to understand the ET process and the CT state. CT states, bound electron and hole pairs, separated in space on different parts of a molecules or different molecules play an ever increasing role in organic optoelectronic devices be they OPV or OLED or in bioimaging.

Our OCTA project will form a new EU-Japan-Taiwan-Brazil network of leading groups and will train a new generation of materials scientists for the development and application of Charge Transfer based materials who can apply their expertise directly in future applications.
Our project covers several aspects of discovering many aspects of the Charge Transfer processes in our life through training and research in our OCTA network.
At present, we have trained 24 scientists, including 12 young researchers from our network.
Additionally, we have published 10 high impact papers in the research area Charge Transfer based organic materials including novel highly efficient Thermally Activated Delayed Fluorescence (TADF) and Room Temperature Phosphorescence organic light-emitting diodes.
The knowledge gain by the project by itself will have a significant impact on the both scientific and non-scientific community. Scientific, because of showing discoveries in the organic electronics area. non-scientific, because those discoveries can be employed in future, cheaper, environmental friendly market products. We will also train our researcher and researchers from outside of the network in breaking through new technologies of flexible electronics.
