Dear All speakers and contributors!

 

Many thanks for your excellent talk and contribution to the 7th TADF-WS! While the time difference and management of the online conference are always tough issues, I really appreciate your great efforts to make the WS successful. I believe we could share cutting-edge research on TADF-OLEDs and related topics. Particularly, it was so nice chance to know the present status of the hot topic of "negative gap”.

 

We wish to continue the WS and we are looking forward to informing you of the next WS.

Message from the Chair

Chihaya Adachi

I am proud to announce that the 7th International TADF Workshop will be held online in December. We believe that online seminars provide a wonderful chance for people to gather from all over the world with minimal barriers to participation—though the time differences can be a bit tricky. We will continue to explore recent results regarding TADF OLEDs and related topics based on charge-transfer complexes this year. Various donor-acceptor interactions have been disclosed to have a rich scientific basis and numerous technological applications, making this area more intriguing each year.

I am very much looking forward to seeing all of you—even if only online—and having fruitful discussions to take our research to the next level. While we cannot meet face to face in Fukuoka, we expect that this attempt to launch exciting online events will pave the way for our post-coronavirus life with a new normal.

We would like to invite a wide variety of researchers from all generations and different research fields related to charge-transfer physics and chemistry. I wish that you will have a wonderful time through this workshop!

Scope and Invited Lecturers

     Through TADF-OLED research and related studies, we have come to recognize that charge-transfer (CT) phenomena are central to the behavior of many organic optoelectronic devices. As such, the scope of the workshop will encompass basic and advance CT science and technologies in light-emitting materials and solid-state devices. In addition to talks about TADF emitters, we would also like to invite other cutting-edge studies on light-emitting materials. We look forward to your contribution to this workshop!
