| マイナスをプラスへ Make Negative a Positive |
藤井 秀司 Syuji FUJII |
| ＜要旨＞Researchers often encounter unexpected phenomena. If the researchers observe the phenomena carefully from different points of view, think deeply and act positively, it should be possible to open doors to exciting new discoveries. |

| 自己組織化による超分子・分子マシンの構築 Construction of Supramolecular Structures and Molecular Machines Based on Self-Organization |
原田 明・山口 浩靖 Akira HARADA and Hiroyasu YAMAGUCHI |
| ＜要旨＞As recently
reported, self-organization of molecules leads to the formation of various
types of supramolecular architectures. Now we suceeded in synthesizing
rotaxanes bearing a ring component on an axial molecule with a dumbbell
shape and supramolecular polymers in high yield. We review recent studies
and describe a new perspective on the construction of supramolecular
assemblies and molecular machines by self-organization. Keywords: Self-Organization / Supramolecular Structure / Rotaxane / Molecular Machine |

| Dissipative Structures in Polymeric System | Olaf KARTHAUS |
| ＜要旨＞Self-organization
is the process of forming dynamic superstructures from more basic units.
Self-organized structures may arise from dissipative structures, which
are not in thermodynamic equilibrium and thus dissipate energy. This
makes these structures inherently difficult to control, but on the other
hand, allows the formation of complex structures from very simple starting
conditions without external guidance. Here, I will review the basic concepts
of dissipative structures and give some examples of how this bottom-up
approach can be used to produce microstructured assemblies. Keywords: Energy Dissipation / Convection / Dewetting / Patterning / Photonics / Electronics |

| 高分子混合系における光誘起相分離と自己秩序化現象 Light-Induced Self-Ordering Phenomena in Polymer Mixtures |
中西 英行・宮田 貴章 Hideyuki NAKANISHI and Qui TRAN-CONG-MIYATA |
| ＜要旨＞Regular structures
resulting from the competition between antagonistic interactions in polymeric
systems were obtained by coupling phase separation with photo-cross-link
reactions and photopolymerization. Here, spatially graded morphology
and morphologies with an arbitrary distribution of length scales were
shown as the two examples for the structures resulting from the competing
interactions in polymer mixtures. Keywords: Interpenetrating Polymer Networks / Photo-cross-link Reaction / Photopolymerization, Competing Interactions, Stationary Nonequilibrium Process / Self Ordering / Graded Co-continuous Structure / Computer-Assisted Irradiation Method |

横山 昌幸 Masayuki YOKOYAMA |
| ＜要旨＞In this review,
applications of self-assembling polymeric materials to drug targeting
systems are explained with a focus on polymeric micelle drug carriers.
The definition and methodologies of drug targeting are briefly summarized,
then examples of self-assembling polymeric drug carrier systems are introduced. Keywords: Drug Targeting / Polymeric Micelle / Self-Assembling Polymer / DDS |

| 自己組織化ゲル：時空間機能をもつ四次元マテリアルとしての高分子ゲル Self-Organizing Gels: Polymer Gels as 4-Dimensional Materials with Spatio-Temporal Function |
吉田 亮 Ryo YOSHIDA |
| ＜要旨＞The design
of novel functional gels with spatio-temporal structures and their applications
has been introduced in a diverse range of research on materials design
utilizing self-organization. We propose a new concept of materials design
to create unique functions by construction of not only self-assembly
based on molecular design but also dissipative structure based on systematic
design in gels. Keywords: Self-Organization / Dissipative Structure / Spatio-Temporal Structure / Polymer Gels / Self-Oscillation |

服部 俊明 Toshiaki HATTORI |
| ＜要旨＞Periodic
microstructure formation occurs spontaneously when polymerization is
initialized by parallel UV light irradiation. The microstructure is thought
to be dissipative structure. Keywords: Self-Organization / Photopolymerization / Parallel UV Light |

| ＜要旨＞Well-defined
hydrophilic polyolefin materials have been newly developed. These polymer
materials disperse in water and form worm-like fibers and nano-particles
through self-organization. Keywords: Water Dispersion / Nanoparticle / Polyolefin / Self-Organization |

| ブロックポリマーの自己組織化によるナノリソグラフィーと電子材料への応用 Nanolithography using Self-Assembling Method and Application to Electronic Devices |
浅川 鋼児 Koji ASAKAWA |
| ＜要旨＞The performance
of electronic devices has greatly improved accompanied by the smaller
feature sizes of their parts. Block copolymer lithography can fabricate
smaller patterns compared to the conventional photolithography because
it forms nano-scale periodic patterns and can be transferred to substrates.
Several kinds of devices are about to be realized. Keywords: Block Copolymer / Self Assembling / Lithography / Resist |

| ＜要旨＞Our research
focuses on the development of energy-related devices such as batteries,
capacitors and organic solar cells by using block copolymer, which is
one of our specialties. We have developed gel-type polymer solid electrolytes
consisting of poly(vinylidenefluoride-co-hexafluoropropylene) block copolymers
for dye-sensitized solar cells. We have successfully proposed the donor/acceptor-type
block copolymers for bulk heterojunction organic thin-film solar cells. Keywords: Energy-Related Device / Block Copolymer / Organic Solar Cell / Polymer Solid Electrolyte / Donor / Acceptor-Type Block Copolymer |

| ソフトインターフェース―高分子界面の新しい機能― Soft Interface: Novel Functions of Polymer Interface |
藤田 雅弘・前田 瑞夫 Masahiro FUJITA and Mizuo MAEDA |
| ＜要旨＞An interface
composed of soft matters such as a polymer is mobile, diffuse, and active.
Such soft interfaces contain water molecules, ions, and substrates. Well-defined
surfaces with densely grafted polymer brushes and colloidal nanoparticles
with such brushes show peculiar interesting properties, which are applicable
for biomaterials and biosensors. Properties and functions of the soft
interfaces are discussed especially on nonionic and anionic polymers. Keywords: Soft Interface / Polymer Brush / Polyelectrolyte / PEG / DNA |
