4. Thermally Activated Delayed Fluorescence from a Spiro-diazafluorene Derivative.

Author

Hiroshi Ohkuma, Tetsuya Nakagawa, Katsuyuki Shizu, Takuma Yasuda, and Chihaya Adachi

Abstract

A spiro compound DPAA-AF combining an electronaccepting diazafluorene unit and an electron-donating bis(diphenylamino) acridane unit has been synthesized and used as an emitter in organic light-emitting diodes. DPAA-AF exhibits efficient thermally activated delayed fluorescence, and a device based on this compound emits blue-greenish electroluminescence with a maximum external quantum efficiency of 9.6%.
