Highly Efficient Heteroleptic Cerium(III) Complexes with a Substituted Pyrazole Ancillary Ligand and Their Application in Blue Organic Light-Emitting Diodes

Compared with red and green organic light-emitting diodes (OLEDs), blue is the bottleneck that restricts the wide development of OLEDs from being the next-generation technology for displays and lighting. As a new type of emitter, a Ce(III) complex shows many satisfactory advantages, such as a short excited-state lifetime, 100% theoretical exciton utilization efficiency, and tunable emission color. Herein we synthesized three heteroleptic Ce(III) complexes Ce(TpMe2)2(dtfpz), Ce(TpMe2)2(dmpz), and Ce(TpMe2)2(dppz) with the hydrotris(3,5-dimethylpyrazolyl)borate (TpMe2) main ligand and different substituted pyrazole ancillary ligands, namely, 3,5-di(trifluomethyl)pyrazolyl (dtfpz), 3,5-dimethylpyrazolyl (dmpz), and 3,5-diphenylpyrazolyl (dppz), and studied their structures and luminescence properties. All the Ce(III) complexes exhibited a near-unity photoluminescence quantum yield both in solution and as a powder with maximum emission wavelengths in the range of 450-486 nm. The OLED employing Ce(TpMe2)2(dppz) as the emitter showed the best performance, including a turn-on voltage, maximum luminance, and external quantum efficiency of 3.2 V, 29 ?200 cd m-2, and 12.5%, respectively.

Process for the preparation of aryl ketones generating reduced amounts of toxic byproducts

An efficient, cost-effective method useful for the production of aryl ketones that minimizes the generation of toxic byproducts is disclosed. The method utilizes a metal triflate salt to catalyze the reaction between the carboxylic acid substrate and the aromatic substrate. The water generated by the reaction is collected and removed during the process.

Characterization of a series of lanthanide amine cage complexes

The preparation and characterization of a series of encapsulated lanthanide amine complexes are discussed. The complexes of Ce, Pr, Eu, and Y with the ligand 1,9-bis(2-aminoethyl)-1,4,6,9,12,14-hexaazacyclohexadecane (referred to as L) have been prepared by using the previously described template approach (using La and Yb) involving the combination of the metal trifluoromethanesulfonate (triflate or trif) salt as the template source, 2 equiv of the tetradentate amine 2,2′,2″-tris(2-aminoethyl)amine (tren), and an excess of the formaldehyde derivative bis(dimethylamino)methane. The reduction potentials of the europium and ytterbium complexes are -0.68 and -1.37 V (vs SCE, in propylene carbonate), respectively, suggesting that this ligand imparts a large stabilization of the +3 oxidation state relative to the +2 state. An analogous lanthanum triflate complex, La(L′)(trif)3 [L′ = bis((2-(bis(2-aminoethyl)amino)ethyl)amino)methane], with one methylene bridge has been prepared and characterized by single-crystal X-ray crystallography. The structure is similar to that of the previously described dibridged complex La(L)(trif)3·CH3CN, and a comparison of these structures suggests possible explanations for the difficulties of obtaining the fully encapsulated lanthanide complex. The complex crystallizes in space group P1 with Z = 2 and a = 9.8448 (13) A?, b = 11.0620 (15) A?, c = 16.8557 (19) A?, α = 73.456 (9)°, β = 73.684 (10)°, and γ = 70.548 (11)°. For 6065 independent data with Fo2 > 3σ(Fo2), full-matrix least-squares refinement with anisotropic thermal parameters for all non-hydrogen atoms (except disordered atoms) converged to unweighted and weighted R factors of 2.4 and 3.0%, respectively. The conductivities of acetonitrile solutions of these complexes suggest 1:1 and 1:2 electrolytes at millimolar concentrations but are highly concentration dependent, indicating that acetonitrile competes effectively with the triflate anions for the free coordination sites on the metal ion. A similar reaction produces in small yield what we believe to be a fully encapsulated ytterbium ion, Yb(L″)(trif)3·CH3CN [L″ = 1,4,6,9,12,14,19,21-octaazabicyclo[7.7.7]tricosane]. In contrast to the di- and monobridged complexes, this new complex does not develop a precipitate in the presence of water, which suggests that the fully encapsulated species is stable toward hydrolysis. The preparation and molecular structure of the first example of a mixed-ligand lanthanide amine complex, Pr(tren)(trien)(trif)3 (trien = triethylenetetramine), is presented in an attempt to characterize the preferred geometry and appropriate bridging units for interconnecting the amine groups. The metal ion is nine-coordinate with tetradentate tren and trien ligands and one coordinated triflate anion. This complex also crystallizes in space group P1 with Z = 2 and a = 9.5259 (12) A?, b = 10.6600 (14) A?, c = 17.0802 (25) A?, α = 74.284 (12)°, β = 76.914 (11)°, and γ = 85.500 (10)°. For 2738 independent data with Fo2 > 3σ(Fo2), a similar refinement converged to unweighted and weighted R factors of 3.9 and 4.6%, respectively.
