Efficient and stable deep-red phosphorescent organic light-emitting diodes based on an iridium complex containing a benzoxazole-substituted ancillary ligand

In the deep red: A biscyclometalated deep-red phosphorescent dopant containing a new ancillary ligand, iridium(III) bis(1-phenylisoquinolinato-N, C2?) (2-(benzo[d]oxazol-2-yl)phenol) (Ir(piq)2bop) has been designed and synthesized. By doping the new complex into Bebq 2 (Bebq2=bis(10-hydroxybenzo[h] quinolinato)beryllium), a saturated red-emitting PHOLED device was obtained. At a luminescence of 100 cd m-2, the device shows efficiencies of 10.3 cd A-1 and 9.1 Lm W-1 with CIE coordinates of (0.67, 0.33). Copyright

A series of red-light-emitting ionic iridium complexes: Structures, excited state properties, and application in electroluminescent devices

A series of ionic diiminoiridium complexes [Ir(piq-C?N) 2(L-N?N)](PF6) were prepared, where piq-C?N is 1-phenylisoquinolinato and L-N?N are bidentate N-coordinating ligands: 2,2?-bipyridine (bpy), 4,4?-dimethyl-2,2?-bipyridine (mbpym), 5,5?-bis(thiopen-2-yl)-2,2?-bipyridine (tbpyt), and 5,5?-bis(9,9-dioctylfluoren-2-yl)-2,2?-bipyridine (FbpyF). X-ray diffraction studies of [Ir(piq)2(mbpym)](PF6) revealed that the iridium center adopts a distorted octahedral geometry. All complexes exhibited intense and long-lived emission at room temperature. The substituents on the 2,2?-bipyridine moieties influence the photophysical and electrochemical properties. The excited states were investigated through theoretical calculations together with photophysical and electrochemical properties. It was found that the excited state of the [Ir(piq) 2(FbpyF)](PF6) complex can be assigned to a mixed character of 3LC (piN?N?pi *N?N), 3MLCT, 3LLCT (pi C?N?pi*N?N), and 3LC (piC?N?pi*C?N). In addition, the alkylfluorene-substituted complex, [Ir(piq)2(FbpyF)](PF6), had relatively high quantum efficiency and good film-forming ability, and it was expected to be a good candidate for lighting and display applications. A nondoped, single-layer device that incorporates this complex as a light-emitting layer was fabricated and red phosphorescence was obtained. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Mild fluorination of chloropyridines with in situ generated anhydrous tetrabutylammonium fluoride

This paper describes the fluorination of nitrogen heterocycles using anhydrous NBu4F. Quinoline derivatives as well as a number of 3- and 5-substituted pyridines undergo high-yielding fluorination at room temperature using this reagent. These results with anhydrous NBu4F compare favorably to traditional halex fluorinations using alkali metal fluorides, which generally require temperatures of ?100 C.

The Chemistry of 5-Oxodihydroisoxazoles. II. Photolysis and Pyrolysis of 2-(Isoquinolin-1-yl)-3-methyl-5-oxo-2,5-dihydroisoxazole-4-carboxylate

Photolysis of ethyl 2-(isoquinolin-1-yl)-3-methyl-5-oxo-2,5-dihydroisoxazole-4-carboxylate occurs by two pathways.The major pathway involves the loss of CO2 to form an imino carbene which may cyclize to form the expected (6) or rearranged (8) imidazo<2,1-a>isoquinolines or react with nucleophiles and recyclize to form the 4-oxopyrimido<2,1-a>isoquinolines.The minor pathway involves electrocyclic ring opening of the isoxazolone and ring closure with or without loss of CO.Pyrolysis leads predominantly to an imino carbene which reacts intramolecularly to give (6) or undergoes insertion into CH bonds.

NHC-Organocatalyzed CAr?O Bond Cleavage: Mild Access to 2-Hydroxybenzophenones

A Truce?Smiles rearrangement of acyl-anion equivalents generated by N-heterocyclic carbene (NHC) catalysis has been achieved. The developed method includes CAr?O, CAr?S, or CAr?N bond cleavage for the formation of a CAr?C bond and enables access to 2-hydroxybenzophenones, an important structural motif that is present in several bioactive natural products. By utilizing this procedure, the alkaloid taxilamine was synthesized in three steps. DFT calculations and control experiments support a classical SNAr mechanism with a catalyst-bound Meisenheimer-type intermediate. The method features mild reaction conditions, excellent functional-group tolerance, and a broad substrate scope, including various classes of (hetero)arenes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C9H6ClN, you can also check out more blogs about19493-44-8

Selective ring opening of linearly and angularly fused triazolium salts

Angularly and linearly fused, 1,2-, and 1,3-disubstituted [1,2,4]triazolium salts were synthesized and reacted with nucleophiles. The sites of attack were found to depend both on the type of annelation and substitution pattern: the linearly fused derivative reacted at the pyridine moiety, whereas the angularly condensed salts were attacked at one of the carbon atoms of the triazole ring, and subsequent ring openings occurred in both cases. For the experienced ambident reactivity a general mechanistic scheme was proposed and the annelation-dependent regioselectivity was rationalised on the basis of an MO approach.

General copper-catalyzed coupling of alkyl-, aryl-, and alkynylaluminum reagents with organohalides

We report the first example of a very general Cu-catalyzed cross-coupling of organoaluminum reagents with organohalides. The reactions proceed for the couplings of alkyl-, aryl-, and alkynylaluminum reagents with aryl and heteroaryl halides and vinyl bromides, affording the cross-coupled products in good to excellent yields. Both primary and secondary alkylaluminum reagents can be utilized as organometallic coupling partners. These reactions are not complicated by beta-hydride elimination, and as a result rearranged products are not observed with secondary alkylaluminum reagents even for couplings with heteroaryl halides under “ligand-free” conditions. Radical clock experiment with a radical probe and relative reactivity study of Ph3Al with two haloarenes, 1-bromonaphthalene and 4-chlorobenzonitrile, having two different redox potentials indicates that the reaction does not involve free aryl radicals and radical anions as intermediates. These results combined with the result of the Hammett plot obtained by reacting Ph3Al with iodoarenes containing p-H, p-Me, p-F, and p-CF3 substituents, which shows a linear curve (R2 = 0.99) with a rho value of +1.06, suggest that the current transformation follows an oxidative addition-reductive elimination pathway.
