Tellurophene-Induced Triplet-Singlet Spin-Flip Acceleration: An Advanced Design for Narrowband Organoboron Emitters with Fast Reverse Intersystem Crossing. [PDF]

Angew Chem Int Ed Engl
Linking 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 ...

Navigating CIE Space for Efficient TADF Downconversion WOLEDs [PDF]

Dyes and Pigments, 2020
Abstract High efficiency orange and green emitting perylene dyes have been synthesized and dispersed in an inert polymer host to form an optical downconversion layer. To avoid dye aggregation and allow controlled colour tuning, this layer was deposited in multiple low-concentration spin-coating steps, directly on top of a high performance blue ...

Benchmarking time-dependent density functional theory for singlet excited states of thermally activated delayed fluorescence chromophores

Physical Review Research, 2022
Thermally activated delayed fluorescence (TADF) is the internal conversion of triplet excitons into singlet excitons via reverse intersystem crossing. TADF can significantly enhance the efficiency of organic light-emitting diodes (OLEDs).
