| Description | From initial work we had shown that uncontrolled molecular conformations lead to very inhomogeneous rates of reverse intersystem crossing which causes fast and slow triplet harvesting leading to poor efficiency and major problems on OLED devices. By using molecules that have locked configurations we remove this problem and can now demonstrate far more efficent OLEDs with stable colour emission and longer lifetime. Two ways to achieve this have been found. This is a major step forward for TADF OLEDs. |
| Exploitation Route | We are working with two leading major International OLED companies and aim to introduce these new materials into our work with them to take our findings further. A new EU Marie Curie project, TADFsolutions was funded in part based on the findings of this project. |
| Sectors | Chemicals Electronics |
| Description | Published results have been taken up by Merck and Samsung in new research directly funded in prof Monkman's group. Further, an Innovate award was funded between PROF Monkman's group, Excyton Ltd (UK) and Fluxim (Switzerland) to develop new highly efficient dual emission layer OLEDs. Original devices fabricated in Durham with Excyton won an Innovation award at he SID Display weeks Conference in the USA. |
