Key Points

This research aims to investigate how local host effects influence the dynamics of thermally activated delayed fluorescence (TADF) in OLEDs.
Analyzed the impact of different host materials on TADF performance
Measured fluorescence characteristics under various conditions
Compared rigidity and polarity of host materials
Identified specific local host characteristics that affect TADF efficiency
Demonstrated a correlation between host rigidity and TADF responsiveness
Found that polarity of the host material influences TADF dynamics significantly

Implication

Findings uncover the influence of local host effects on TADF dynamics in OLEDs, suggesting implications for device efficiency.

Abstract

Donor-acceptor (D-A) type thermally activated delayed fluorescence (TADF), a key technology of proposed Gen3 organic light emitting diodes (OLEDs), is highly sensitive to the rigidity and polarity of the local...
