meso–meso Directly-linked trimeric and pentameric porphyrin–hexaphyrin hybrid arrays 5 and 6 comprising of electron-deficient porphyrin units were prepared by cross-condensation of monomeric and dimeric electron-deficient meso-formyl porphyrins with a tripyrrane. The solid-state structures of 5 and 6 have been determined by single crystal X-ray diffraction analysis. The latter is the largest crystal structure of meso–meso linked multiporphyrinic array analogues reported to date.

Abstract We report on the synthesis of a new bismuth aryloxide molecule Bi[OC6H4(CH2C6H5)-2]3 (1), which was characterized by NMR and IR spectroscopy as well as single-crystal X-ray diffraction analysis. A characteristic structural feature is the dimeric unit with a central Bi2O2 core resulting from μ-binding phenolates. In addition, both bismuth atoms show a Bi⋅⋅⋅π arene interaction with a quite short Bi⋅⋅⋅πcentroid distance of 3.11 Å in the solid state.

Results from the study of highly structure-confined YBa 2 Cu 3 O 7−x superconductors synthesized by different coprecipitation processes are presented, with the superconducting samples made from oxalic-nitrate salts demonstrating higher critical temperature and critical current in comparison with solid reaction oxides. Among the measured samples, the critical temperature, T c , is typically 90–95 K (T c (maximum)=105 K) and the critical current is 1.2 – 1.9 × 104 A/cm 2 at 4.5 K and 1200 A/cm 2 at 78 K. Peak patterns similar to those of solid-state reactions by X-ray diffraction analysis have also been found although these spectra show considerably broadness. Superconductors resulted from coprecipitation techniques with no calcining (heat-treatment) processing can be attained. Further studies on producing single-crystal with increasing critical current and temperature are discussed.

Tetraarylanthracenes containing several fluoro groups were synthesized using the ruthenium-catalyzed C–O or C–F arylation with arylboronates and their structural and spectroscopic studies were conducted. The RuH2(CO)(PPh3)3-catalyzed C–O arylation of aromatic ketones was found to be effective for the introduction of aryl groups containing multiple fluoro groups. Anthracenes possessing fluorinated aryl groups were prepared in two steps from 1,4,5,8-tetramethoxyanthraquinone by C–O arylation and reduction of the carbonyl groups. A tetraphenylanthracene containing a fluorinated anthracene moiety was also prepared using C–F phenylation of octafluoroanthraquinone. Single-crystal X-ray diffraction analysis showed that the positions of fluoro groups on the tetraarylanthracenes lead to notable difference in the crystal packing structures. The larger difference between the tetraarylanthracenes was observed in the fluorescence spectra in the solid state than those in chloroform.
