Three new 1,8-naphthyridine-based thermally activated delayed fluorescence (TADF) emitters, 2,7-di(9,9-dimethylacridin-10(9H)-yl)-1,8-naphthyridine (DMAC-ND), 2,7-di(10H-phenothiazin-10-yl)-1,8-naphthyridine (PTZ-ND) and 2,7-di(10H-phenoxazin-10-yl)-1,8-naphthyridine (PXZ-ND), were designed and synthesized. They possessed twisted structures and small Delta E-ST, which could make them show excellent TADF and AIDF properties. Consequently, multi-color organic light-emitting diodes (OLED) based on emitters DMAC-ND, PTZ-ND and PXZ-ND were fabricated, which could achieve a maximum external quantum efficiency (EQE) of 14.1, 13.4 and 13.0%, respectively. Moreover, all devices exhibited relatively low turn-on voltages and low efficiency roll-off ranging from 4.5% to 20% at the luminance of 1000 cd m(-2) probably owing to the microsecond-scale delayed photoluminescence (PL) and AIDF properties of the emitters. Notably, a DMAC-ND-based non-doped device reached the luminance of 20000 cd m(-2) easily at the voltage of 6.5 V, and exhibited very low efficiency roll-off of 4.5% at the luminance of 1000 cd m(-2) and 33.6% at the luminance of 10000 cd m(-2).

(NDI)Ni-2 catalysts (NDI=naphthyridine-diimine) promote cyclopropanation reactions of 1,3-dienes using (Me3Si)CHN2. Mechanistic studies reveal that a metal carbene intermediate is not part of the catalytic cycle. The (NDI)Ni-2(CHSiMe3) complex was independently synthesized and found to be unreactive toward dienes. Based on DFT models, we propose an alternative mechanism that begins with a Ni-2-mediated coupling of (Me3Si)CHN2 and the diene. N-2 extrusion followed by radical C-C bond formation generates the cyclopropane product. This model reproduces the experimentally observed regioselectivity and diastereoselectivity of the reaction.

Synthesis, Characterization and Structure of Tribromo(2-phenyl-1,8-naphthyridine)gold(III)

Neutral tribromo(2-phenyl-1,8-naphthyridine)gold(III), AuBr3(N-N), has been prepared by reaction of KAuBr4 with the ligand in CHCl3/C2H5OH and was characterized by H-1 NMR spectroscopy and X-ray diffraction. The molecular and crystal structure of AuBr3(N-N) center dot 0.5 THF (triclinic, P1, a = 11.314(2), b = 12.350(3), c = 14.628(3) angstrom, alpha = 107.96(3), beta = 98.86(3), gamma = 107.29(3)degrees, Z = 4, 173 K) shows coordination of the N-8 nitrogen atom situated in the unsubstituted pyridine ring to the planar four-coordinate Au-III center. Whereas the AuBr3N best planes and the coordinated naphthyridine rings are not far from orthogonal (omega similar to 105 degrees), the phenyl substituents were found in the crystal with a ca. 22 degrees dihedral angle relative to the naphthyridine plane. Intermolecular Au center dot center dot center dot Br distances close to the sum of the van der Waals radii indicate very weak interactions to form a quasi-dimeric arrangement in the crystal.

Testing a simple approach for theoretical evaluation of radiolysis products in extraction systems. A case of N,O-donor ligands for Am/Eu separation

In this paper, we studied the irradiation and ageing effect on the extraction properties of N, N’-diethyl-N, N’-di(p-hexylphenyl)-1,1′-phenantroline-4,7-dichloro-2,9-dicarboxamide (1) and 2,5,9,12-tetra(n-hexyl)benzo[f] quinolino-[3,4-b]-[1,7]-naphthyridine-6,8(5H,9H)-dione (2) towards Am(III) and Eu(III). DFT calculations were applied to estimate the probable ways of radiolysis for (1) and (2). Degradation products were identified by high-resolution ESI-MS. The interaction of (1) and (2) with the products of solvent radiolysis was established to be the most probable mechanism of ligand destruction.
