Using low temperature scanning tunneling microscopy (STM), we observed a single molecule magnet, Tb3+ double decker molecule TbPc2 (Pc = phthalocyaninato), adsorbed on a perovskite type transition metal oxide SrVO3 ultrathin film. TbPc2 molecules adsorbed intact and flat on two surface reconstructions of SrVO3, (2–√×2–√)-R45° and (5–√×5–√)-R26.6°, with different configurations. High resolution STM images revealed that the adsorption configurations were governed by the adatom structure of each surface reconstruction according to the proposed adsorption configurations.

The effects of depositing Pd alloy nanoparticles (NPs) on an amine-functionalized Fe-metal organic framework (MOF; MIL-88B-NH2) were investigated, with the aim of developing a photo-switchable bifu...

A cyclic (alkyl)(amino)bromoborane (CAABBr) was synthesized by a reaction of the corresponding hydroborane with bromine in the presence of triethylamine. Reduction of the resulting CAABBr with Li p...

Significant improvement in cycling endurance and operating voltage dispersion has been accomplished by the addition of Cu-doped triglyme (G3) to the HfO2 film of the Cu/HfO2/Pt-type conducting-bridge random access memory (CB-RAM); both the Vset distribution and the charge-transfer resistance (Rct) values were significantly reduced.

We study resonant frequencies of water sessile drops in various oils. The resonant frequency is experimentally obtained as the frequency shift of the scattered laser light, using an optical heterodyne technique. The resonant frequency is explained by the capillary wave propagating along the meridian curve of the drop with the fixed-end boundary condition at the three-phase contact line, although the sessile drop in air considerably deviates from the fixed-end boundary condition. We study this point further by observing the vibration directly with a fast video camera, and by analyzing the contour of the snapshot near the contact line. The results agree with the resonant frequency analysis results, where the number of half waves in the meridian curve of the water sessile drop is an integer when the drop is in oil, while in air, it deviates considerably from an integer.

Boryl-substituted diphosphene was reduced by treatment with an excess amount of Li to form dianionic diboryldiphosphanediide 2. Reaction of 2 with MeI resulted in methylation at the two negatively charged phosphorus atoms. NMR spectroscopy, X-ray crystallographic analysis, and DFT calculations revealed that the coordination of DMAP to 2 induced significant pπ–pπ interactions between P and B atoms. The UV–vis spectrum of 2·[DMAP]2 exhibited characteristic absorption at λmax = 380 nm, which could be assigned to an intramolecular charge transfer from the π-orbital of the B−=P–P=B− moiety to the π*-orbital of the DMAP ligand as per TD-DFT calculations.

Strong Bronsted-base-catalyzed addition reactions of alkylazaarenes with vinylsilanes are reported. The reactions of alkylpyridines and their analogues with vinylsilanes proceed in moderate to high yields in the presence of catalytic amounts of LiTMP, LiCl, and MS 4A. This is a general method that can be applied to catalytic addition reactions of alkylazaarenes with vinylsilanes.

Micromixing enables highly selective mono addition of aryllithiums to dialdehydes. Because the unchanged formyl group in the products can be used for further transformations, the present approach serves as a powerful method for protecting-group-free synthesis.

The structure–activity relationship of carbon-supported Co catalysts was investigated in solvent-free aerobic oxidation of ethylbenzene under microwave irradiation. A single-site Co species show specifically high catalytic activity under microwave irradiation compared to conventional heating, while the oxidation is not accelerated by microwave when Co nanoparticle catalysts are used.

The serious side effects of aminoglycosides and the spread of aminoglycoside-resistant strains have restricted the clinical application of aminoglycosides. A compound with the identical mode of action with aminoglycosides and with different molecular skeleton would be an alternative drug for aminoglycosides. In this study, we constructed an SPR-based high-throughput screening system for the discovery of such compounds.

An electrophilic 5-endo-trig cyclization of β,β-difluoro-o-sulfonamidostyrenes was performed in 1,1,1,3,3,3-hexafluoropropan-2-ol using a Ag(I) catalyst and N,O-bis(trimethylsilyl)acetamide. In this process, vinylic C–F bond activation was achieved via silver-catalyzed β-fluorine elimination, accompanied by C–N bond formation, which led to the synthesis of 2-fluoroindoles.
