Aggregation-induced Emission Luminogens for Non-doped Organic Light-emitting Diodes

Organic Light-emitting Diodes (OLEDs) are solid-state devices that transform electrical energy into light. OLEDs are considered the next generation technology for high-resolution flexible displays and solid state lighting, attracting intense scientific and industrial interest.

Design of efficient thermally activated delayed fluorescence materials for pure blue organic light emitting diodes.

Qisheng Zhang et al.

Journal of the American Chemical Society, 134(36), 14706-14709 (2012-08-31)

Efficient thermally activated delayed fluorescence (TADF) has been characterized for a carbazole/sulfone derivative in both solutions and doped films. A pure blue organic light emitting diode (OLED) based on this compound demonstrates a very high external quantum efficiency (EQE) of

Pt(II) metal complexes tailored with a newly designed spiro-arranged tetradentate ligand; harnessing of charge-transfer phosphorescence and fabrication of sky blue and white OLEDs.

Kuan-Yu Liao et al.

Inorganic chemistry, 54(8), 4029-4038 (2015-04-08)

Tetradentate bis(pyridyl azolate) chelates are assembled by connecting two bidentate 3-trifluoromethyl-5-(2-pyridyl)azoles at the six position of pyridyl fragment with the tailored spiro-arranged fluorene and/or acridine functionalities. These new chelates were then utilized in synthesizing a series of Pt(II) metal complexes
