    Pt-containing meta- and para-linked poly(phenyleneethynylene)s were synthesized by the dehydrochlorination coupling polymerization of PtCl2(PBu3)2 with m- and p-diethynylbenzenes. The formed polymers were sintered at 900 °C to obtain Pt-graphene hybrids, whose structures were examined by Raman scattering spectroscopy, X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD) measurements. Shapes─facets, terraces, and steps─with average diameters of 2.0-3.4 μm were observed by field emission scanning electron microscopy (FE-SEM). The Pt-graphene hybrids moderately adsorbed CO2 and O2 and slightly adsorbed ethylene and methane. Epoxidation of stilbene was carried out using Pt-graphene hybrids as catalysts to obtain stilbene oxide.

    Trisubstituted 1,3,5-tri(benzimidazolyl)benzene derivatives were synthesized from ʟ-alanine, ʟ-valine, ᴅ-valine and glycine, and their self-assembling behavior and stimuli-response in solution and gel states were evaluated. Circular dichroism/UV-vis absorption spectroscopic and dynamic light scattering measurements revealed that the compounds formed H-aggregates via intramolecular hydrogen bonding and π-π stacking interactions in nonpolar solvents such as CHCl3, whereas collapse of the aggregates was confirmed by MeOH addition. Quantum mechanical calculations and molecular dynamics simulations also supported aggregation in CHCl3. Rheological analysis and morphology observation revealed the formation of a fibril like structure by further assembling of aggregates at a high concentration in CHCl3.

    Platinum-containing macrocycles (platinacycles) have gained attention due to their unique photoelectric properties. In the present study, a novel conjugated platinacycle was synthesized by the dehydrochlorination coupling reaction of a bipyridine dichloroplatinum(II) complex and a 3,6-diethynylcarbazol derivative. The structure of the platinacycle was confirmed by 1H/13C, 1H-1H COSY, HMQC, HMBC, DEPT NMR spectroscopies in conjunction with DFT calculations, IR spectroscopy and MALDI-TOF mass spectrometry. The platinacycle exhibited a UV-vis absorption around 540 nm assignable to ligand-ligand charge transfer, and birefringence in DMF, possibly due to alignment of molecules.

    L-Tyrosine diketopiperazine (DKP) derivative 1 was synthesized, and the aggregation and photoluminescence behaviors were examined. A solution of 1 in tetrahydrofuran (THF) gradually became viscous at room temperature, and turned into the gel state 5 hours after preparation, as confirmed by dynamic viscoelasticity measurement. A solution of 1 in THF exhibited photoluminescence. Fibrous patterns were observed by transmission electron, atomic force and fluorescence microscopies. Dynamic light scattering, semiempirical molecular orbital and density functional theory calculations, as well as molecular dynamics simulations, indicated aggregate formation. This was attributed to intermolecular hydrogen bonding, mainly between the DKP moieties and partly between the urethane moieties, resulting in π-orbital overlap of the terminal phenyl groups leading to photoluminescence.

    The topology of polymers affects their characteristic features, i.e., their microscopic structure and macroscopic properties. However, the topology of a polymer is usually fixed during the construction of the polymer chain and cannot be transformed after its determination during the synthesis. In this study, topology-transformable block copolymers that are connected via rotaxane linkages are introduced. We will present systems in which the topology transformation of block copolymers changes their 1) microphase-separated structures and 2) macroscopic mechanical properties. The combination of a rotaxane structure at the junction point and block copolymers that spontaneously form microphase-separated structures in the bulk provides access to systems that cannot be attained using conventional covalent bonds.

The dinuclear complex (PdMC)2 was prepared by one-step macrocyclization followed by the double palladation reaction. 1 H NMR analysis and UV/Vis measurements revealed the formation of a doubly threaded pseudo[3]rotaxane by the complexation of (PdMC)2 with 2 equivalents of 2,6-disubstituted pyridine 3 through double metal coordination. The treatment of (PdMC)2 with 2 equivalents of 4-vinylpyridine (VP) afforded a doubly threaded [3]rotaxane cross-linker (PdMC-VP)2 . Radical co-polymerization of VP and t-butylstyrene in the presence of (PdMC-VP)2 afforded a stable rotaxane cross-linked polymer (RCP). An elastic RCP was also prepared by using n-butyl acrylate as a monomer. The obtained RCPs exhibited higher swelling ability and higher mechanical toughness compared with the corresponding covalent cross-linked polymers.

    We synthesised palladium and platinum complexes possessing cyclic and acyclic pincer-type polyaromatic ligands and investigated their structural effect on the catalysis. The pincer-type bis(6-arylpyridin-2-yl)benzene skeleton was constructed via Kröhnke pyridine synthesis under transition metal-free conditions on gram-scale quantity. Ligand structure significantly influenced catalytic activity toward the platinum-catalysed hydrosilylation of diphenyl acetylenes, despite the ligand-independence of the conformations and electronic properties of these complexes.

    To evaluate the 'slide-ring' effect in a rotaxane cross-linked network, we incorporated mechanochromophores into static and rotaxane cross-linking points and compared the mechanochromisms exhibited by the obtained polymers. This novel strategy reveals a molecular-level phenomenon with visible color changes as well as enabling quantitative electron paramagnetic resonance measurements.

    Silk fibroin (SF) is a fascinating natural biomaterial that exhibits remarkable mechanical properties and biocompatibility. Meanwhile, biological adhesive materials have gathered much attention as biomedical and ecofriendly materials as a result of their characteristic properties. Herein, we report the excellent adhesive function of enzymatically modified SF. The tyrosine residues of SF were successfully converted to the dihydroxy-l-phenylalanine (DOPA) unit using tyrosinase as a biocatalyst. The content of DOPA was evaluated by amino acid composition analysis. Adhesive functions of DOPA-modified SF (DOPA-SF) among several material surfaces including mica, paper, polypropylene, wood, and silk film were elucidated by lap shear tests. Fourier transform infrared measurements demonstrated that the adhesion strength of DOPA-SF was not directly related to the β-sheet formation of silk molecules. This ecofriendly and facile method offers a new perspective for fabricating natural adhesive materials for various application areas.

    Polypepties containing glycine-proline-glycine tripeptide sequence and tyrosine unit were synthesized via chemoenzymatic polymerization. The obtained polypeptides were used as the crosslinker to form silk fibroin gel. As results, the amount of tyrosine unit affected the gelation time, whereas the amount of tripeptide affected the resilience of the formed gel. In short, we found the sequences of formed polypeptides affected to the network polymers.

    本研究では,アミノ酸より得られる、親水性内部空間を有するらせん構造を形成するポリマーを合成し、生成ポリマーの光学特性,刺激応答性,液晶性,分子認識性などの新規機能性高分子としての機能評価を目的としている。今年度は具体的に以下のような内容について検討を行った。まず、主鎖にアゾベンゼン部位を有する新規光応答性ポリフェニレンエチニレン、種々の共役ユニットからなる異なる共役持続長を有するポリフェニレンエチニレンおよび側鎖に重合性部位を有するポリフェニレンエチニレンの合成を行った。今回新たに合成したポリマーはいずれも非極性溶媒中で、親水性内部空間を有するらせん構造を形成することを種々の測定により明らかにした。アゾベンゼンを有するポリマーは光照射に応答して、その高次構造を大きく変化することを見出した。種々の共役長を有するポリマーはその共役ユニットの違いにより、それぞれ異なる内孔の大きさのらせん構造を形成することを見出し、その共役長により異なる蛍光色を示すことを明らかとした。さらに、側鎖に重合性部位を有するポリマーではらせん構造を側鎖間の反応によって、固定化できることを見出した。さらに、α-プロパルギルアミノ酸より合成した新規置換ポリアセチレン誘導体が、イオン応答性を示し、また二次構造の変化に伴うソルバトクロミズムを示すことも明らかとした。これらの結果は親水性内部空間を有するらせん高分子の設計指針およびその構造の応用に関して多くの知見を得るものであり、研究の進展に非常に有益なものであったと考えられる。

    In order to achieve the artificial molecular motors that move and rotate the molecule in one direction as seen in the biological system, in this study the micro tubular polymers and rotaxanes were organized to produce the macroscopic movement like a molecular motor as the results of synergistic effect of these molecular devices. In particular we examined, 1) construction of small tubular macromolecules by polymerization of rigid chiral unit and application of their inner pore to molecular recognition, 2) construction of rotaxane -based molecular device and their hybridization, 3) the creation of molecular motor, and 4) construction of dynamic supramolecular materials based on the hybridization of molecular motor and organic/inorganic materials.
