Effect of Hydration on the Very Slow Droplet–Lamellar Transition in Dioleylsulfosuccinate/Decane/Water System: A Small Angle X-ray Scattering Study
S. K. Ghosh, N. Ichiyanagi, H. Okabayashi,* A. Yoshino, T. Takeda, and C. J. O’Connor
[Full Text PDF(J-STAGE)]
Free Access Article
 | In the sodium dioleylsulfosuccinate (SDOleS)–decane–water system with various molar ratios of water and SDOleS (X = [H2O]/[SDOleS]), the droplet lamellar transition occurs very slowly and spontaneously depending upon X. |

Aromaticity and Conjugation in Sapphyrin and Orangarin
J. Aihara* and M. Makino
[Full Text PDF(J-STAGE)]
 | Aromaticity and ring-current diamagnetism in two expanded porphyrins, sapphyrin (1) and orangarin (2), were analyzed theoretically. Main macrocyclic conjugation pathways in these π-systems were predicted consistently from the bond resonance energies (BREs) and the π-current density maps. |

Configuration of Adsorbed Phases and Their Evolution to Absorbent States in the CH4–O2 Catalytic Reaction
J. Cortés* and E. Valencia
[Full Text PDF(J-STAGE)]
 | Through kinetic Monte Carlo simulations of the catalytic oxidation of methane, it is shown that the temporal evolution of the adsorbed phase to absorbent states is interpreted by an exponential decay of production (Ri ≈ e−kt). |

Kinetic Study of Singlet-Oxygen Quenching by Caffeic Acid and Related Phenols
K. Ohara,* Y. Ichimura, and S. Nagaoka
[Full Text PDF(J-STAGE)]
 | The second-order rate constants (kQ) of singlet-oxygen quenching by caffeic acid and related phenols were measured in ethanol and toluene. These phenols deactivate singlet-oxygen by physical quenching at kQ = 106–107 M−1 s−1 through a charge-transfer transition state. |

Purity Effects on the Charge-Transport Properties in One-Dimensional TPP[CoIII(Pc)(CN)2]2 (TPP = Tetraphenylphosphonium and Pc = Phthalocyaninato) Conductors
S. Yamashita, T. Naito, and T. Inabe*
[Full Text PDF(J-STAGE)]
Purity effects on the electrical resistivity in TPP[Co(Pc)(CN)2]2 with a one-dimensional metallic electronic system have been examined. No dependence on the impurity content has been observed, suggesting that the thermally activated behavior is dominated by charge disproportionation.

Three-Dimensional Morphological Chirality Induction in Polythiophene Polymer Deposit Using a Magnetic Field
Y. Tanimoto,* A. Shinyama, and K. Omote
[Full Text PDF(J-STAGE)]
In the presence of a 4-T vertical magnetic field, left-handedly and right-handedly twisted polymer deposits are obtained when prepared by anodic oxidation.

Chloride Complexation of Zr and Hf in HCl Investigated by Extended X-ray Absorption Fine Structure Spectroscopy: Toward Characterization of Chloride Complexation of Element 104, Rutherfordium (Rf)
H. Haba,* K. Akiyama, K. Tsukada, M. Asai, A. Toyoshima, T. Yaita, M. Hirata, K. Sueki, and Y. Nagame
[Full Text PDF(J-STAGE)]
Chloride complexation of Zr and Hf in HCl is investigated by EXAFS spectroscopy to characterize chloro complexes of element 104, rutherfordium (Rf). Together with the anion-exchange results, it is suggested that Rf forms the same complexes as those with Zr and Hf, [Rf(H2O)8]4+ → [RfCl6]2−, and that the affinity of Cl− for these metal ions is in the order of Rf > Zr > Hf.

High-Resolution Solid-State NMR Studies of Natural Abundant 15N Observed in Halogen-Bridged One-Dimensional Complexes, [NiX(chxn)2]X2 and [Pd(chxn)2][PdX2(chxn)2]Y4 (chxn = (1R,2R)-Diaminocyclohexane; Y = X (Halogen), NO3, and ClO4)
N. Kimura,* T. Shimizu, and R. Ikeda
[Full Text PDF(J-STAGE)]
 | We performed solid-state 15N NMR measurements of chxn ligands in halogen-bridged Pd and Ni complexes with a 1-D structure. Spectra obtained for 15N bonded to Pd2+, Pd4+, and Ni3+ were clearly separated from each other. |

1H and 27Al NMR Study of Li[AlH4] + Ti Compounds in Solution
S. Takeuchi, H. Senoh, S. Zhang, H. T. Takeshita, T. Kiyobayashi,* Q. Xu, and N. Kuriyama
[Full Text PDF(J-STAGE)]
 | A broad sextet signal in the 1H NMR spectrum of Li[AlH4] in THF-d8, centering at 2.75 ppm with J/Hz = 176, was assigned to the signal from [AlH4]−. Also investigated were the reactions of Li[AlH4] with TiCl3 or Ti(OBu)4 in THF. |

How Are Non-Bonded G···Z (Z = O, S, and Se) Distances at Benzene 1,2-, Naphthalene 1,8-, and Anthracene 1,8,9-Positions Controlled? An Approach to Causality in Weak Interactions
S. Hayashi and W. Nakanishi*
[Full Text PDF(J-STAGE)]
[Supporting Information]
 | It is often difficult to demonstrate causality in weak interactions. Categories in weak interactions are sometimes quite different from those in strong interactions. Factors to control the non-bonded G···Z distances in 8-G-1-RZC10H6 are analyzed as a typical case, which is controlled not by the G···Z interaction but by the repulsive interaction between R and H at the 2-position. |

Synthesis and Photochemical Characteristics of Amphiphilic Enediyne Dendrimers

Synthesis and Structural Analysis of Triphenylmethane-Based Alkanecarboxamides and Their Assembly into Nanometer-Size Fibrous Objects
H. Houjou,* T. Koga, M. Akiizumi, I. Yoshikawa, and K. Araki
[Full Text PDF(J-STAGE)]
 | The molecular assembly of a series of C3-symmetric trialkanecarboxamides was systematically investigated. The length of the alkyl chains considerably influenced the mode of crystal growth, which in turn caused a drastic change from microcrystals to fibrous objects with 100-nm thickness. |

Photolysis of 1,2-Naphthoquinone in Oxygen-Doped Argon Matrix at Low Temperature
T. Itoh, J. Tatsugi,* and H. Tomioka*
[Full Text PDF(J-STAGE)]
[Supporting Information]
 | Photolysis of 1,2-naphthoquinone (1) in argon matrix gave bis(ketene) 2, which isomerized to isomeric ketene 3 upon continued irradiation, along with a small amount of inden-1-one (4). When the irradiation was carried out in argon matrix doped with 20% oxygen, six- and eight-membered cyclic peroxide 5 and 6 presumably formed by trapping of initial diradical generated by α-cleavage of 1 upon photoexcitation by molecular oxygen were detected. |
