The present invention relates to specific transition metal catalysts and their use in chemical reactions.

An organic light-emitting device includes: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode, the organic layer including an emission layer. The emission layer includes at least one organometallic compound of Formula 1, and at least one selected from a second compound and a third compound, where the organometallic compound, the second compound, and the third compound are different from each other. When the emission layer comprises both the second compound and the third compound, the second compound and the third compound form an exciplex, and the organometallic compound and the second compound and/or the third compound do not form an exciplex:

Provided are an organometallic compound represented by Formula 1 and an organic light-emitting device including the same. The organic light-emitting device includes a first electrode; a second electrode facing the first electrode; an organic layer between the first electrode and the second electrode and including an emission layer; and at least one organometallic compound represented by Formula 1.

A series of highly luminescent cyclometalated rhodium(III) complexes, with photoluminescence quantum yields up to 0.65 in thin films, have been designed and prepared. The strong luminescence property is realized by the judicious choice of a strong σ-donor cyclometalating ligand with lower-lying intraligand state and the ability to raise the d-d excited state. This is the first report to demonstrate the capability of rhodium(III) complexes as high efficient light-emitting materials for organic light-emitting devices. Compelling external quantum efficiencies of up to 12.2% and operational half-lifetime of over 3,000 hours have been achieved.

In one aspect, phosphine compounds comprising three adamantyl moieties (PAd.sub.3) and associated synthetic routes are described herein. Each adamantyl moiety may be the same or different. For example, each adamantyl moiety (Ad) attached to the phosphorus atom can be independently selected from the group consisting of adamantane, diamantane, triamantane and derivatives thereof. Transition metal complexes comprising PAd.sub.3 ligands are also provided for catalytic synthesis including catalytic cross-coupling reactions.

Compounds are described and characterized that bind guanine quadruplexes of DNA or RNA. Binding data and inhibition of growth data of five cancer cell lines are presented.

Provided herein, in part, is a new class of sterically bulky, easily prepared N-heterocyclic carbene (NHC) ligands of Formula I, or a salt, solvate, geometric isomer, or stereoisomer thereof. The ligands are readily synthetically accessible exploiting the cost-effective, modular alkylation of anilines. The NHC ligands of the present disclosure can be used to prepare effective catalysts with transition metals, including the compound of Formula II, or a salt, solvate, geometric isomer, or stereoisomer thereof. In certain embodiments, the transition metal is Pd.
