TADF is achieved in an integrated system of dopant, host and transport materials. CYNORA is developing such systems with its customers and partners. Our R&D covers all development aspects from simulation to device fabrication, constantly collaborating with the costumers at all development stages. This efficient approach ensures a fast progress towards the best material set for the customer.
Photophysics & Simulation
Our ideas for new materials are studied first using DFT (density functional theory). With such quantum chemical calculations, it is possible to predict important properties of emitters, like their color or their TADF potential. Promising candidates are then successively selected for synthesis. Besides this screening, DFT calculations are also performed to gain a better understanding of exceptionally good material families and to support the interpretation of complex experimental results.
The synthesis division is responsible for the production of our materials for the customers, as well as for the research and development of new and innovative luminescent materials. Depending on the requirements, synthesis of up to several hundred grams is possible. At the end of the material synthesis, sublimation steps are performed to achieve the highest possible purity for vacuum- based processing.
Detailed material analytics
In addition to the testing of purity, the analytics division is responsible for the complete material characterization from photophysics to electrochemistry. Results from these measurements deliver essential information for device fabrication.
Device optimization and fabrication
CYNORA combines a broad screening of materials in OLED devices with detailed studies towards the customer targets. Consequently, highly promising materials are identified and the stack architecture is constantly being improved.
