Room-temperature phosphorescent materials that emit light in the visible (red, green, and
blue; from 400 to 700 nm) have been a major focus of research and development during the …

Although organic light‐emitting devices have been commercialized as flat panel displays
since 1997, only singlet excitons were emitted. Full use of singlet and triplet excitons …

A novel class of luminescent cyclometalated gold (III) alkynyl complexes has been
demonstrated to possess EL properties and has been employed in the roles of …

Osmium (II) complexes possessing β‐diketonate, quinolinate, diimine, and C‐linked pyridyl
azolate chelates reveal interesting structural and photophysical properties. Spectroscopic …

A novel host material for efficient green and red electrophosphorescence devices is
obtained by adopting the new molecular strategy of nonconjugated linkage of carbazole and …

Intramolecular interactions between ligands have been successfully applied as a novel tool
for controlling various properties of a series of cis, trans-[Re (dmb)(CO) 2 (PR3)(PR '3)]+ …

Since the intersystem crossing from singlet state to triplet state is effectively promoted by
strong spin-orbit coupling, neutral rhenium [Re (I)] tricarbonyl complexes show …

Highly efficient electrophosphorescence from organic light-emitting devices based on a Cu I
complex,[Cu (DPEphos)(Dicnq)] BF 4 (⁠ DPEphos= bis [2-(diphenylphosphino) phenyl] …

As an extension of our previous study, three sky-blue homoleptic iridium (III) complexes 1–3
with fluorine-free phenylimidazole ligands were synthesized and their photophysical …

In contrast to mononuclear iridium (III) complexes, dinuclear iridium (III) complexes have
been less well studied, especially as dopants in phosphorescent organic light-emitting …
