Learn how to use ADF to optimize molecules for Thermally Activated Delayed Fluorescence (TADF) for optimal conversion efficiency in OLED materials with our new advanced tutorial. TADF optimization tutorial
Optimizing TADF emission Long-range corrected density functional theory can ameliorate some of the known problems of DFT dealing with charge transfer states (e.g. push-pull systems). These systems are of great interest for organic electronics, and...
The Os(fipz)(tfa)(CO)3 (tfa = trifluoroacetate, fipz=3-trifluoromethyl-5-(1-isoquinolinyl)-1,2-pyrazole) complex shows excitation-dependent emission quantum yield. The higher-energy excitation (< 340 nm) contributes more to phosphorescence than fluorescence, implying stronger intersystem crossing (ISC) for highly excited singlet states. Theoretical...
The theoretical luminescence efficiency of fluorescent-only organic light-emitting diodes (OLEDs) can be increased from 25% to 100% by harvesting triplet excitons with transition metal complexes, most notably Ir(III). In a recent J. Phys. Chem. C...
Mr. Kento Mori of Ryoka (now MOLSIS), reselling ADF in Japan, have conducted a case study on fac-tris(2-phenylpyridine)iridium (Ir(ppy)3), bis(4,6-difluorophenylpyridinato-N,C2)picolinatoiridium (FIrpic) and bis(2-benzo[b]thiophen-2-yl-pyridine)(acetylacetonate)iridium(III) (Ir(btp)2(acac)), molecules of great interest in the development of Organic Light Emitting Diodes...
Organic light emitting diodes (OLEDs) are used in displays in smartphones and televisions, and future applications include general lighting and flexible screens. Phosphorescent emitters typically achieve higher quantum efficiencies. At the University of Queensland’s Centre...
