Tellurophene-Induced Triplet-Singlet Spin-Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing. [PDF]
Angew Chem Int Ed EnglLinking an auxiliary dibenzo[b,d]tellurophene unit markedly accelerates exciton spin conversion in multi‐resonance‐type thermally activated delayed fluorescence emitters. Owing to the heavy‐atom effect of tellurium, the corresponding OLEDs retain remarkably high external electroluminescence quantum efficiencies exceeding 25% even at an exceptionally ...

Photophysical Characterisation of Thermally Activated Delayed Fluorescence (TADF) Materials
Display and Imaging, 2017 In this work we present a brief characterization of thermally activated delayed fluorescence (TADF) emitters and describe the spectroscopic methods used to investigate them. Both steady state and time-resolved methods are presented. The effect of oxygen on delayed fluorescence is described.
