    1. Photoinduced Charge Separation Catalyzed by Manganese Oxides onto a Y-Shaped Branching Acceptor Efficiently Preventing Charge Recombination

      Dr. Kentaro Yamamoto and Prof. Dr. Kazuo Takatsuka

      Version of Record online: 20 JAN 2017 | DOI: 10.1002/cphc.201601237

      Why not get back together? Photoinduced charge separation dynamics mediated by Mn oxides, electron-wavepackets, and protons transfer in a coupled manner through mutually different pathways to different sites of a Y-shaped branched acceptor. This molecular shape and the presence of a doped Ca atom prevent the electron–proton pair created returning to the Mn oxide.

      Meaningful prediction: A series of dyes containing thiophene and thieno[3,2-b]thiophene units as π-spacers and six different types of acceptor groups have been designed. The photoelectrical properties of the dyes, considering their potential application in dye-sensitized solar cells, were investigated using DFT/TDDFT methods. The dye incorporating a TCA acceptor group was calculated to exhibit the largest open-circuit voltage.

      Version of Record online: 18 JAN 2017 | DOI: 10.1002/cphc.201601190

      Thumbnail image of graphical abstract

      Taking a shortcut: Ca codoping in YAlO3:Ce single crystal is able to shorten the scintillation decay time (see Figure), though this is also accompanied by a general reduction of the scintillation efficiency. The lower efficiency is mostly related to reabsorption and energy transfer phenomena involving Ce3+ and Ce4+ ions.

      Thumbnail image of graphical abstract

      Folding to function: We report a new design of an anionic protein surfactant, SP16, capable of tuning foaming behaviour by pH or salt. The high negative charge at pH 6 and above restrict its ability to fold into an α-helical conformation entailing low foaming propensity, but the presence of salt (NaCl) was found to effectively screen negative charge, thus leading to its folding and the restore of its foaming activity.

      Version of Record online: 16 JAN 2017 | DOI: 10.1002/cphc.201601072

      Thumbnail image of graphical abstract

      The resonance Raman spectra of the nucleobase uracil are analyzed in the short-time approximation calculated with multiconfigurational methods. A minimal active orbital space that leads to a qualitatively correct description of the resonance Raman spectrum of uracil should encompass parts of the σ/σ* bonding/anti-bonding orbitals of the pyrimidine ring. This is traced to the considerable entanglement between the σ/σ* bonding/anti-bonding as well as valence π/π* orbitals in the excited-state electronic structure of uracil.

      Active or not: Although in situ XRD measurements suggest the formation of a Mg2FeH6 metastable phase during the dehydrogenation of Fe loaded MgH2, further investigation suggest that Mg2FeH6 does not present any catalytic influence for the system. This is evident from the observation that dehydrogenation of Mg2FeH6-loaded MgH2 occurs at considerably higher temperatures compared to Fe loaded MgH2.

      Jacobus van’t Hoff proposed in 1874 that molecules have three-dimensional structures. A novel reaction microscope employs advanced single-particle imaging detectors that measure the full three-dimensional velocity distribution of correlated electrons and (fragment) ions emitted from an excited molecule. In their Minireview (DOI: 10.1002/cphc.201100107), M. H. M. Janssen and co-workers illustrate the wealth of detailed information that can be obtained about the interplay between shaped laser fields, femtosecond dynamics, ionization processes and multichannel pathways in three-dimensional (chiral) molecules.
