Tetrameric and octameric 2,6-pyridylene ethynylene oligomers linked to a beta-D-glucopyranoside template through an o-phenylene linker were prepared and studied for their higher-order structure. These oligomers formed chiral helical structures through intramolecular hydrogen bonding between the ethynylpyridine moiety and the glucoside template. The rigidity of the o-phenylene linker stabilizes the helical structure to improve its CD activity and resistance against protic surroundings. Furthermore, the helical stabilization was enhanced by the addition of Cu(OTf)2 and Zn(NO 3)2 salts.

Five ligands as monosubstituted derivatives of the basic skeleton of 2,6-bis(2-benzimidazyl)pyridine were synthesized, and characterized by NMR and IR spectra along with the X-ray structure analysis. Their complexation gave a set of hexacoordinate Fe(II) complexes showing predominantly the diamagnetism until ambient temperature. Some temperature-independent paramagnetism along with an onset of the spin transition is also detected.

The synthesis of extended heteroarenes via the acid-promoted dehydrocyclisation of arylamino-anthraquinones is examined as an approach to highly conjugated electron-acceptor materials and eventually to heterographene nanoribbons. Whilst the latter perspective is found to remain challenging, the former is exemplified by the synthesis of extended tetraazaheterocycles bearing solubilising alkyl substituents.

Luminescent materials with red emission are promising materials for optoelectronic devices and biological sciences. However, their synthesis is often complicated. In this work, we developed a facile approach to generating red-emissive luminogens with aggregation-induced emission (AIE) characteristics from commercially available reactants. The new compounds, abbreviated PN-BTZ-Cz and DP-BTZ-Cz, were prepared by coupling 4,7-dibromobenzo[c][1,2,5]thiadiazole with (1-naphehyl)phenylamine or diphenylamine followed by the reaction of the monobromo-substituted compounds with carbazole. Although all of the reactants were non-AIE-active, PN-BTZ-Cz and DP-BTZ-Cz showed AIE characteristics. This suggested that the AIE chromophores were generated in situ through the reactions. PN-BTZ-Cz and DP-BTZ-Cz were soluble in common organic solvents and showed red emission with high fluorescence quantum yields of 42.2 and 38.3% in the film, respectively. They were thermally and morphologically stable, as revealed by their high decomposition temperature (up to 327 C) and glass-transition temperature (up to 120 C). Nondoped organic light-emitting diodes with a configuration of ITO/HATCN/TAPC/PN-BTZ-Cz or DP-BTZ-Cz/Bphen/Liq/Al were fabricated using these compounds as emitting layers, which emitted red electroluminescence at a low turn-on voltage (down to 2.8 V) with a maximum external quantum yield of up to 2.7% and a small efficiency roll-off.

Single crystal X-ray diffraction analysis of Pd(O2CCF2CF3-O)2(dppf) 1 shows that one of the two unidentate fluoropropanoates shows a rare bonding behavior with significant ? character for the C=Ocoord bond whereas the C-Opendant bond is long and bears a basic function. Complex 1 serves as a metalloligand towards AgO2CCF2CF3 to give PdAg(mu-O2CCF2CF3)2(O2CCF2CF3-O)(dppf) 2, which is fluxional in solution showing interchanges of the bridging and unidentate fluoropropanoate groups. Being an unusually stable Pd(II) carboxylate, 1 also serves an effective entry to mixed-metal carboxylates.

Temperature variation of the effective magnetic moment for a pentacoordinate [Co(bzimpy)Cl2] complex shows a pronounced deviation from linearity below 120 K. Quantitative analysis based on the diagonalisation of the spin Hamiltonian matrices gave the set of magnetic parameters: gx=2.501, gy=2.622, gz=1.476, D/hc=71.7 cm-1, E/hc=1.4 cm-1, alphaTIP=0.98×10-9 m3 mol-1 and zJ/hc=-0.184 cm-1 (SQUID data). The extreme value of the axial zero-field splitting parameter D shows that the magnetic anisotropy determined by the non-spherical distribution of the spin density is enhanced by the low symmetry of the pentacoordinate chromophore. For the [Mn(bzimpy)Cl2]·1/2 MeOH analogue, only a moderate ZFS is found (D/hc=-2.7 cm-1).

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Quality Control of Pd2(DBA)3. Introducing a new discovery about 52409-22-0, Name is Pd2(DBA)3

We report herein the preparation, the electrochemical, the absorption and the emission properties of a new heteroleptic bisterpyridine ruthenium complex. The first terpyridine is functionalized, on the 4? position, by a phosphonic acid group and the second terpyridine bears in the 4? position a tert-thiophenyl unit attached via an ethanyl spacer. The latter complex was tested in dye-sensitized solar cells using the liquid electrolyte (I2/LiI/tert-butylpyridine/propylene carbonate) or the solid poly(3-octylthiophene) as a hole conductor. It displays an improved photovoltaic photoconversion efficiency compared to the analogous complex in which the tert-thiophene is directly linked to the terpyridine ligand. This study shows that the covalent attachment of a thiophene residue on the sensitizer is a promising strategy for the development of solid-state dye-sensitized solar cells and it highlights the benefit of introducing a non-conjugated spacer between the thiophenyl unit and the polypyridine ruthenium sensitizer.
