Suppressing dimer formation by increasing conformational freedom in multi-carbazole thermally activated delayed fluorescence emitters

Twisted carbazoles and shallow dihedral angles provide a defence against dimer formation that adversely affects OLED performance.

Effect of dendron structure on the luminescent and charge transporting properties of solution processed dendrimer-based OLEDs

The energy transfer, PLQY, charge mobility, and OLED performance of blend films of first generation Ir(ppy)3-cored light-emitting dendrimers and dendrimeric TCTA-based hosts are found to be dependent on the dendrons and surface groups used.

Near-infrared cyclometalated iridium(iii) complexes with bipolar features for efficient OLEDs via solution-processing

Double gain, a bipolar feature NIR iridium(iii) complex with both hole and electron transporting group to improve the OLED performance.

Energy level engineering of PEDOT:PSS by antimonene quantum sheet doping for highly efficient OLEDs

AMQS doping can effectively enhance Ir(ppy)3-based OLED performance by adjusting the energy level of PEDOT:PSS.

Effects of steric encumbrance of iridium(iii) complex core on performance of solution-processed organic light emitting diodes

Attachment of bulky groups to the surface of irdium(iii) complex core obstructs its charge trapping ability and reduces OLED performance.

Identification of host–guest systems in green TADF-based OLEDs with energy level matching based on a machine-learning study

Machine-learning algorithms were used to quantify TADF-based OLED performance and obtain a relationship between a TADF-based OLED device and its efficiency.

Minimization of solid-state conformational disorder in donor–acceptor TADF compounds

Thermally activated delayed fluorescence (TADF) compounds with a flexible donor–acceptor structure suffer from conformational disorder in solid-state, which deteriorates their emission properties as well as OLED performance.
