π-Conjugated Polymers, (Th(R)–CH=CH–Th(R))n (Th(R) = 3-Alkylthiophene-2,5-diyl; R = Octyl, Decyl, and Dodecyl): Preparation of Dibromo Monomers and the Polymers
Takakazu Yamamoto,* Akira Kumagai, Hisashi Kokubo, and Yoshiyuki Nakamura
[Full Text PDF(J-STAGE)] [Supporting Information] Open Access Article
| Th(R)–CH=CH–Th(R) type π-conjugated polymers (R = octyl, decyl, and dodecyl) have been prepared and their self-assembling behavior has been investigated. |

Development of a New System for Photocatalytic Water Splitting into H2 and O2 under Visible Light Irradiation
Ryu Abe
[Full Text PDF(J-STAGE)] Open Access Article
A novel photocatalytic system that splits water into H2 and O2 under visible light was realized using a two-step photoexcitation system composed of a shuttle redox couple and two different semiconductor photocatalysts.

Material Design and High-Pressure Synthesis of Novel A-Site-Ordered Perovskites AMn3Al4O12 (A = Y, Yb, and Dy) with Square-Planar-Coordinated Mn3+
T. Saito,* T. Tohyama, P. M. Woodward, and Y. Shimakawa
[Full Text PDF(J-STAGE)] Open Access Article
| A-site-ordered perovskites AMn3Al4O12 (A = Y, Yb, and Dy) were designed using the program SPuDS, and were synthesized with a high-pressure technique. The obtained compounds showed antiferromagnetic ordering of the high-spin Mn3+, whereas Y3+/Dy3+ stayed paramagnetic. |

Synthesis and Chiral Recognition Ability of a Poly(phenylenevinylene)-Encapsulated Amylose Derivative
K. Tamura, N. S. M. Sam, T. Ikai, Y. Okamoto, and E. Yashima*
[Full Text PDF(J-STAGE)] Open Access Article
Novel chiral packing material composed of a rod-like poly(phenylenevinylene)-encapsulated amylose tris(3,5-dimethylphenylcarbamate) was prepared through macromolecular reaction. The chiral recognition ability of the obtained material was evaluated as the chiral stationary phase for high-performance liquid chromatography (HPLC).

Phase Transitions in Soft Matter Induced by Selective Solvation
A. Onuki,* R. Okamoto, and T. Araki
[Full Text PDF(J-STAGE)] Open Access Article
| We study phase transitions in aqueous fluid mixtures, polyelectrolytes, and ionic surfactants induced by selective solvation. Cross-sectional profiles of the densities of hydrophilic cations (left) and hydrophobic anions (right) in a phase-separating aqueous mixture at the critical compositon (top) and at an off-critical composition (bottom). |

Alkoxyphenyl-Substituted Symmetric Liquid Crystalline Diamantane Derivatives
T. Gushiken, S. Ujiie, T. Ubukata, and Y. Yokoyama*
[Full Text PDF(J-STAGE)] [Supporting Information] Open Access Article
| Eleven novel thermotropic rod-shaped liquid crystals composed of diamantane and the alkoxyphenyl or alkanoyloxyphenyl groups on both ends of a molecule have been synthesized. They showed liquid crystalline properties at considerably high temperatures of up to 340 °C. |

Synthesis of a Doubly Strapped Light-Harvesting Porphyrin Bearing Energy Donor Molecules Hanging on to the Straps: An Attempt toward Macroscopic Control over Molecular Conformation that Affects the Efficiency of Fluorescence Resonance Energy Transfer
S. Ogi, K. Sugiyasu,* and M. Takeuchi*
[Full Text PDF(J-STAGE)] [Supporting Information] Open Access Article
We report that a macroscopic stretching operation can dynamically control the molecular conformation of a light-harvesting molecule in an elastomeric film; as a consequence, we have succeeded in controlling its photophysical function that is very much a molecular level phenomenon.
