We investigated the light emitting processes of thermally activated delayed fluorescence (TADF) emitters for OLED in terms of structural dynamics using time-resolved infrared vibrational spectroscopy. As a result, we found the strong correlation between TADF activity and structural change upon intersystem crossing.
