Journal ArticleDOI
Recent advances in white organic light-emitting materials and devices (WOLEDs).
TL;DR: The types of materials (small molecules and polymers) that have been used to fabricate WOLEDs are described and a range of device architectures are presented and appraised.
Journal ArticleDOI
Triplet harvesting with 100% efficiency by way of thermally activated delayed fluorescence in charge transfer OLED emitters.
Fernando B. Dias,Konstantinos N. Bourdakos,Vygintas Jankus,Kathryn C. Moss,Kiran T. Kamtekar,Vandana Bhalla,Vandana Bhalla,José Santos,Martin R. Bryce,Andrew P. Monkman +9 more
TL;DR: It is shown that triplet states can be harvested with 100% efficiency via TADF, even in materials with ΔEST of more than 20 kT (where k is the Boltzmann constant and T is the temperature) at room temperature.
Journal ArticleDOI
New electroluminescent bipolar compounds for balanced charge-transport and tuneable colour in organic light emitting diodes: triphenylamine–oxadiazole–fluorene triad molecules
Kiran T. Kamtekar,Changsheng Wang,Sylvia Bettington,Andrei S. Batsanov,Igor F. Perepichka,Martin R. Bryce,Jin H. Ahn,Mohammad Rabinal,Michael C. Petty +8 more
TL;DR: In this paper, the authors describe bipolar 2,5-diaryl-1,3,4-oxadiazole-fluorene hybrids which incorporate triphenylamine or carbazole units within the π-electron system, viz. compounds 7, 8, 14 and 16.
Journal ArticleDOI
Tuning the intramolecular charge transfer emission from deep blue to green in ambipolar systems based on dibenzothiophene S,S-dioxide by manipulation of conjugation and strength of the electron donor units.
Kathryn C. Moss,Konstantinos N. Bourdakos,Vandana Bhalla,Vandana Bhalla,Kiran T. Kamtekar,Martin R. Bryce,Mark A. Fox,Helen L. Vaughan,Fernando B. Dias,Andrew P. Monkman +9 more
TL;DR: The efficient synthesis and photophysical properties of a series of ambipolar donor-acceptor-donor systems is described where the acceptor is dibenzothiophene S,S-dioxide and the donor is fluorene, carbazole, or arylamine.
Journal ArticleDOI
Efficient Deep-Blue Electroluminescence from an Ambipolar Fluorescent Emitter in a Single-Active-Layer Device
Alison L. Fisher,Katharine E. Linton,Kiran T. Kamtekar,Christopher Pearson,Martin R. Bryce,Michael C. Petty +5 more
TL;DR: In this paper, a new ambipolar molecule based on a carbazole−fluorene−oxadiazole triad was reported, which reveals a deep-blue electroluminescence with CIE coordinates of (0, 157, 0.079).
