| <Abstract> This
article is an overview of our investigations of smectic liquid crystal
arrangements of rod-like helical polysilanes with narrow molecular weight
distributions and their mixtures with different molecular
weights. Some of the theoretically predicted molecular arrangements,
e.g., the micro-segregated smectic phase with alternating thick and thin
smectic layers rich in the long
polymer and short polymer, respectively, were observed by synchrotron
radiation small-angle X-ray scattering (SR-SAXS) and atomic force microscopy
(AFM) observations on the thin film surface. The formation of these unusual
molecular arrangements are entropically driven because these liquid crystal
formations of non-polar homopolymers conform mainly to their molecular
shapes, not their specific intermolecular interactions. The future investigation
of the fabrication of metal nano-wire grid polarizers using the smectic
phase as an template is also disscussed. Keywords: Liquid Crystal / Smectic Phase / Helical Structure / Polysilane / Entropy-Driven / Alignment Layer / Wire Grid Polarizer |

| <Abstract> I
describe here what I would like to do with an own group recently launched
by exploiting my experience and expertise that I have acquired for the
last four and a half years in the U. S.. For research, I will work on
exploring organic catalysts to enable ring-opening polymerization of
lactide in bulk and to show stereoselectivity at ambient condition. Development
of functional biodegradable polymers will also be addressed for application
in bulk biomaterials such as scaffolds for regenerative medicine. My
research style will be oriented toward emphasizing patents and collaboration
with industries not only for commercialization but also for the local
community based on my past work experience. For education, especially
in English studies, I would like to have students learn how to communicate
and socialize with people rather than just how to speak English. Finally,
I would like to try many things from research to social activities with enthusiasm and ambition leading my small but promising
group. Keywords: Polymer Synthesis / Ring-Opening Polymerization / Biodegradable Polymers / Organic Catalysts / Self-Assembly |

| 超分子主体的设计与原位聚合 | 石田康博 |
| <Abstract> In
supramolecular liquid crystals, molecules are confined in peculiar environments,
where ordered alignment and certain mobility are realized at the same
time. Considering these characteristics, the idea of multi-component
liquid crystal as zeolite analogue seems quite reasonable. Taking advantages
of their characteristic properties, such as structural order, certain
mobility of molecules, and easy access to various components, we have
succeeded in applying two-component liquid crystals as chiral organic
frameworks for selection, sensing, and transformation of small organic
substrates. Keywords: Liquid Crystals / Supramolecular Chemistry / Cross-Linking / Template Reactions / Host-Guest Chemistry / Chiral Recognition |

| 具有特殊性能的纳米生物材料的开发与医疗领域中的应用 | 冈村阳介 |
| <Abstract> Much
attention has recently been focused on the research field of nanotechnology.
Nano-sized structures with a large specific surface area (m2/g) in devices
lead to high reaction efficiencies on the interfaces. As a result, size,
weight and cost of the devices are reduced. For example, ultra-thin films
(nanosheets) have been developed as novel nanoseparation membranes and
flexible nanosensors for electrochemical and photochemical applications.
However, it may be hard to use them for biomedical applications due to
complicated preparative methods. In our laboratory, we develop innovative
and unique nanobiomaterials for medical applications by simple methodologies
based on macromolecular chemistry and molecular assembly. Especially,
we investigate the relationship between properties of the nanobiomaterials
(shape, size, thickness, interface and viscoelasticity etc.) and their
potential abilities. Keywords: Macromolecular Chemistry / Molecular Assembly / Nanobiomaterials / Drug Delivery / Nanosheets / Nanoparticles |

| 通过界面协同效果来控制的高分子复合体的物性 | 鸟饲直也 |
| <Abstract> The
physical properties and structures of polymer composites are examined
to control them using interfacial synergy produced at the involved material
interface. At present, the polymer composites with solid particles and
the composite polymer thin films on flat substrates are studied as a
main research subject. In this study, the polymer physical and chemical
adsorption on the solid particles or flat substrates is utilized to produce
interfacial synergy in each system, since the polymer adsorption could
produce a great variety in the chain conformation, surface coverage,
adsorbed amount, etc., of the polymer adsorbed at the interface. The
physical properties of these polymer composites are investigated by producing
different situation in interfacial properties with the adsorbed polymer.
Moreover, the up-to-date scattering techniques with neutron and synchrotron
X-rays are applied for structural observation on these polymer composites to understand their physical properties at
the molecular level. Keywords: Interfacial Synergy / Soft-Matter Composite / Polymer Adsorption / Solid Particle / Flat Substrate / Polymer Composite / Polymer Thin Film / Neutron and X-Ray Scattering |

| 精密甘氨酸共聚物的设计与合成及其生物功能的控制 | 三浦佳子 |
| <Abstract> Polymers
with molecular recognition abilities are investigated. The polymers with
pendant saccharides, called “glycopolymers”, have been reported to show
the strong molecular recognition abilities to the sugar recognition protein
due to the multivalent effects.
In order to develop the glycopolymers with higher functionalities, I
have focused on the polymer properties.
The glycopolymers are prepared with living radical polymerization, and
the molecular recognition abilities are able to be tuned by molecular
weight and sugar densities. The hybrid glycopolymers via living radical
polymerization are able to be applied to biosensors and bioseparation.
In addition, the molecular recognitions are also investigated with polymer
nanoparticles. In the polymer nanoparticles, the 3D-structure and physical
properties are facilely controlled, and not only saccharide structure
but also polymer properties are shown to be important in molecular recognition
abilities. In the future experiment, the polymers with molecular recognition
abilities will be investigated by featuring polymer techniques and properties. Keywords: Molecular Recognition / Glycopolymer / Polymer Nanoparticle |
