Hyperbranched polymer (poly-1a) with sulfonic acid groups at the end of chains was successfully synthesized.
Interpenetration reaction of poly-1a with a hyperbranched polymer with acryloyl groups at the end of chains (poly-1b)
as a cross-linker afforded a tough electrolyte membrane. The poly-1a and the resulting electrolyte membrane showed
the ionic conductivities of 7x10-4 and 8x10-5 S/cm, respectively, at 150 ºC under dry condition. The ionic conductivitiesof the poly-1a and the electrolyte membrane exhibited the VTF type temperature dependence. And also, both poly-1aand the resulting electrolyte membrane were thermally stable up to 200 ºC.

NAKASAKA, Takahiro UNO, Masataka KUBO, Osamu YAMAMOTO* : Journal of Power Source 163, pp. 252-257,
2006
New comblike polymers such as a homopoloymer (poly-4) of 3,5-bis[poly(ethylene glycol) methyl ether (350,n=7.2)]styrene (4) and an alternating copolymer (poly-4/TCNQ) of 4 with 7,7,8,8-tetracyanoquinodimethane (TCNQ)
were prepared as a plasticizer for the poly(ethylene oxide) (PEO)-LiN(CF3SO2)2 electrolyte, and the ionic
conductivities, thermal property, electrochemical and thermal stabilities, and mechanical property for the
comblike-based polymer electrolytes, composed of the comblike polymers, poly(ethylene oxide) (PEO), and
LiN(CF3SO2)2, were investigated. The polymer electrolytes containing an alternating copolymer poly-4/TCNQ showed
the higher ionic conductivity, better thermal stability and better mechanical stability than that containing a
homopolymer poly-4, due to the presence of an aromatic ring and a polar cyano group of the TCNQ unit.

Solid Polymer Electrolytes Based on Poly(1,3-diacetyl-4-imidazolin-2-one), Hiroyuki MITSUDA, Takahiro UNO,
Masataka KUBO, Takahito ITOH : Polymer Bulletin 57, pp. 313-319, 2006
Solid polymer electrolytes composed of a homopolymer (poly(AcIM)) of 1,3-diacetyl-1,4-imidazolin-2-one(AcIM) and lithium bis(trifluoromethanesulfonimide) (LiTFSI) or of copolymers (poly(AcIM/VC)) of AcIM withvinylene carbonate (VC) and LiTFSI were prepared and their ionic conductivities and thermal properties were
investigated. For the polymer electrolyte of the poly(AcIM) with LiTFSI, the highest ionic conductivity was found at
the [Li]/[O] ratio of 1/3 with the values of 8.5 x 10-5 S/cm at 80 ºC and 1.7 x 10-6 S/cm at 30 ºC, respectively. In thepolymer electrolyte of poly(AcIM/VC) with LiTFSI at the [Li]/[O] ratio of 1/3, the ionic conductivity increased withincreasing VC unit content in the copolymers, and the highest ionic conductivity was found at the AcIM/VC ratio of
39/61 (mol%) with the values of 7.0 x 10-4 S/cm at 80 ºC and 6.7 x 10-5 S/cm at 30 ºC, respectively. This copolymer
electrolyte showed a linear relationship between the ionic conductivity and the reciprocal of the temperature, indicativeof the system decoupled from the segmental motion of the polymer.

Synergistic effect of red phosphorus, novolac and melamine ternary combination on flame retardancy ofA―31

poly(oxymethylene), Hatsuhiko HARASHINA, Yoshihisa TAJIMA*, Takahito ITOH : Polymer Degradation andStability 91, pp. 1996-2002, 2006
New flame retardant system for poly(oxymethylene)（POM） has been studied. The combination of red
phosphorus with novolac and melamine was found to act as an effective flame retardant of POM. The base POM
exhibited very low limiting oxygen index (LOI) value of 15.3, while the flame retarded POM gave remarkably high
LOI value of 37.5 and UL94 V-1 ranking without dripping at 0.8mm thickness. The results of cone calorimetry,
thermogravimetry and FTIR analysis suggested that the flame retarding mechanism is the intumescent char formationin the condensed phase. Novolac having a phenolic hydroxyl group is miscible with POM, and in the flaming process,red phosphorus yields phosphine and its acidic product such as phosphoric acid due to hydrolysis and oxidation
reactions. In addition, all of novolac, melamine and phosphine are able to readily react with formaldehyde generatingfrom POM during burning to give the reinforced and cross-linked char network through the polyaddition andpolycondensation reactions. Therefore, the red phosphorus/novolac/melamine ternary combination system could
synergistically promote the high flame retardancy of POM without the flaming drips.

Masataka KUBO, Yuichi AIHARA*, Atsuo SONAI* : ECS Transactions (Proton Exchange Membrane Fuel Cells 6) 3,
pp. 113-121, 2006
Two different molecular weight hyperbranched polymers (HBP-PA(L) and HBP-PA(H)) with phoshonic acidgroups at the chain ends were successfully synthesized. The ionic conductivities of the low molecular weight
HBP-PA(L) and the high molecular weight HBP-PA(H) were found to be 1.3x10-4 and 6.4x10-5 S/cm, respectively, at
135 ºC under dry condition, and showed the VTF type temperature dependence. And also, both polymers were
thermally stable up to 300 ºC, and they had suitable thermal stability as an electrolyte in the polymer electrolyte fuel cell
operating under dry condition.

Red, green and blue fluorescent poly(arylene vinylene)s were prepared by Wittig reaction. Polycondensation oftetraethoxysilane (TEOS) was carried out in the presence of a mixed solution of these polymers to give a silica hybrid
in which RBG fluorescent polymers were immobilized without phase separation. White light emission was observed
from the ternary polymer blend/silica hybrid.

Theoretical Study of Electronic Structures of [Peroxoporphinato]manganate [Mn(P)(O2)]– Anion, Yasunori
YOSHIOKA, Hideaki SANO, Masaki MITANI: Bull. Chem. Soc. Jpn., 79 (8), pp. 1201–1210, 2006
Geometries and electronic structures of the quintet and septet states of the [Mn(P)(O2)]– (P: porphinato) anion
were theoretically investigated. Four local minimum geometries with two side-on additions of O2 to MnP, 1 (5B2) and 3(7A2), and two end-on additions of O2, 2 (5A’’) and 4 (5A’), were found. One of the side-on forms, 1, corresponds to thatobserved by X-ray crystallographic study. 3 is a septet state with higher spin than the quintet states of 1, 2, and 4. Eachof the two end-on forms has the corresponding transition state with the side-on geometry. Energy differences among 1,
2, and 3 are less than 1 kcal mol–1. The electronic structures of four local minimum states were essentially different. 1
has an electronic structure presented as [MnIII(O22–)]–. 2 has antiferromagnetically coupled diradical character presented
by the formal chemical formula of [MnII•(O2•–)]–. 3 has ferromagnetically coupled diradical character. 4 is presented by[MnII(O2–)]–.

Electronic Structures of Heme(Fe)–Dioxygen Complex as an Intermediate Model of Dioxygen Reduction in
Cytochrome c Oxidase, Yasunori YOSHIOKA, Masaki MITANI, Hiroyuki SATOH: Internet Electron. J. Mol. Des., 5(8), pp. 447–459, 2006
We have previously proposed the O2 reduction mechanism that the protons transfer from the K–channel to theactive site of CcO. The second proton transfer to the hydroperoxy intermediate FeOOH did not lead the OO bondcleavage. It has been recently reported that the addition of the proton induces the OO bond cleavage to yield the
productive H2O molecule and the oxo intermediate Fe=O, being inconsistent with our results. We have started thisA―34

study to confirm whether the OO bond cleavage occurs or not upon the proton addition. We concentrated our study tothe changes of the electronic structures of the heme a3 part throughout the sequential additions of the protons and anelectron during the process of the O2 reduction. We employed a model that is composed of porphyrin without any
substituents, Fe, and an imidazole as His376. We added sequentially protons and an electron to the heme(Fe)–dioxygen
complex. The geometrical parameters were fully optimized without any constraints. The unrestricted hybrid
exchange–correlation functional B3LYP method was used. The Wachters double zeta basis set was employed for Fe
atom. The 6–31G* basis set was used for C, N, and H atoms, and the 6–311+G* for O atom. All calculations werecarried out using the program package Gaussian 98. The proton addition to FeOO (H2) to yield FeOOH (H3) causes
the electron transfer from the porphyrin ring to FeOOH moiety, giving the porphyrin–radical cation. The additional
proton to FeOOH (H4) leads to the OO bond cleavage, yielding the hydrogen bonded complex of an oxo heme
(compound I) and a H2O molecule. The bonding characters of FeOOH in H3 and H4 are identical, even though theelectronic structures of the porphyrin rings in H3 and H4 are different. However, the proton addition to FeOOH (H3)does not lead to the OO bond cleavage. The protonated heme(Fe)–dioxygen complexes are effective models toinvestigate the reduction mechanism of a O2 molecule in CcO.

A B3LYP Study of Proton Transfer Path within a Complex of Benzene Radical Cation and Water Cluster, Moriyuki
SHIMIZU, Emi YAMASHITA, Masaki MITANI, Yasunori YOSHIOKA: Chem. Phys. Lett., 432, pp. 22–26, 2006
We made a theoretical study of the proton transfer path from C6H6•+(H2O)4 to C6H5•(H2O)4H+ with a planar
cyclic geometry of (H2O)4H+ by the hybrid density functional B3LYP method. The proton transfer proceeds in athree-step manner. In the first step, the proton in C6H6•+(H2O)4, moves from the terminal H2O molecule in the (H2O)4cluster to yield a (H2O)3H+ cluster. In the last third step, one H2O molecule leaves from C6H6(OH)• in
C6H6(OH)•(H2O)3H+ to yield a C6H5•(H2O)4H+ complex through the H-abstraction by the OH radical. It is found thatthe proton transfer and redistribution from p to r of the radical electron proceed separately.

Highly Activated Vinyl Hydrogen in a Significantly Twisted Styrene, Hajime MORI*, Takafumi MATSUO*,
Yasunori YOSHIOKA, Shigeo KATSUMURA*: J. Org. Chem., 71 (24), pp. 9004–9012, 2006
The novel example of a vinylic hydrogen more reactive than a benzylic hydrogen was found by treatment of atwisted styrene derivative with a strong base followed by D2O quenching. In this paper, the full details of the examplesof the highly activated vinyl hydrogens in twisted styrene derivatives are described, with a discussion on the correlation
between the reactivity of the vinyl hydrogens and the magnitude of the twist. The highly reactive vinyl hydrogens could
be rationalized by considering the novel orbital interaction between the  * orbital of the benzene ring and the  orbitalof the vinylic C–H bond in the twisted styrene derivatives.

Density Functional Study on Geometrical Features and Electronic Structures of Di- -oxo-Bridged [Mn2O2(H2O)8]q+
with Mn(II), Mn(III), and Mn(IV), Masaki MITANI, Yohei WAKAMATSU, Takeharu KATSURADA, Yasunori
YOSHIOKA: J. Phys. Chem. A, 110 (51), pp. 13895–13914, 2006
We report the geometrical features and electronic structures of di- -oxo-bridged Mn–Mn binuclear complexes
with H2O ligands [Mn2O2(H2O)8]q+ in the iso- and mixed-valence oxidation states. All of the combinations among
Mn(II), Mn(III), and Mn(IV) ions are considered the oxidation states of the Mn–Mn center, and the changes inmolecular structure induced by the different electron configurations of Mn-based orbitals are investigated in relation toA―35

the oxygen-evolving complex (OEC) of photosystem II. The stable geometries of complexes are determined by using
the hybrid-type density functional theory for both of the highest- and lowest-spin couplings between Mn sites, and thelowest-spin-coupled states are energetically more favorable than the highest-spin-coupled states except in the case of
the complexes with the Mn(II) ion. The coordination positions of H2O ligands at the Mn(II) site tend to shift from theoctahedral positions in contrast to those at the Mn(III) and Mn(IV) sites. The shape of the Mn2O2 core and the distances
between the Mn ions and the H2O ligands vary depending on the electron occupations of the octahedral eg orbitals on
the Mn site with an antibonding nature for the Mn–ligand interactions, indicating the trend as Mn(II)–O > Mn(III)–O
and Mn(IV)–O, O–Mn(II)–O > O–Mn(III)–O > O–Mn(IV)–O among the iso-valence Mn2O2 cores, andO–Mn(lower)–O < O–Mn(higher)–O within the mixed-valence Mn2O2 core, and as Mn(II)–OH2 and Mn(III)–OH2 >Mn(IV)–OH2 for the axial H2O ligand. The optimized geometries of model complexes are compared with the X-ray
structure of the OEC, and it is suggested that the cubanelike Mn cluster of the active site may not contain a Mn(II) ion.
The effective exchange integrals are estimated by applying the approximate spin projection to clarify the magnetic
coupling between Mn sites, and the superexchange pathways through the di- -oxo bridge are examined on the basis of
the singly occupied magnetic orbitals derived from the singlet-coupled natural orbitals in the broken-symmetry state.
The comparisons of the calculated results between [Mn2O2(H2O)8]q+ in this study and [Mn2O2(NH3)8]q+ reported by
McGrady et al. suggest that the symmetric pathways are dominant to the exchange coupling constant, and the crossed
pathway would be less important for the former than it would for the latter in the Mn(III)–Mn(III), Mn(IV)–Mn(IV),and Mn(III)–Mn(IV) oxidation states.

Sumiya, Nobuyuki Imanishi and Yasuo Takeda : Solid State Ionics 177, pp. 535-540, 2006
Epitaxial films of the perovskite, La0.8Sr0.2CoO3 (LSC), for SOFCs cathode were deposited on yttria-stabilized
zirconia (YSZ) single crystals by pulsed laser deposition method. The films were characterized by thin-film X-ray
diffraction measurement, atomic force microscopy (AFM), transmission electron microscope (TEM), and ac
impedance spectroscopy. The film orientations depend on the substrate planes. The LSC films on the YSZ (100) and(111) substrates showed the (110) orientation with different twin structures, while those on the YSZ (110) had (100) and(112) orientations. Surface morphology of the films also depends on the substrate orientations. These films showed
different electrode properties depending on the orientations. The relationships between the properties, the filmorientations, surface morphology, and lattice misfit are discussed.

An anomalous thermal expansion in the perovskite system, Gd1−xSrxMnO3 (0 ≤ x ≤ 0.3), A. Hirano, F. Hirano, T.
Matsumura, N. Imanishi and Y. Takeda : Solid State Ionics 177, pp. 749-755, 2006
The thermal expansion behavior of sintered samples of Gd1−xSrxMnO3 (X=0.0–0.4) was studied. The sinteredbodies in this system showed negative thermal expansion over a wide temperature range. The detailed crystal structurerefinements with respect to temperature showed that the volume of the orthorhombic perovskite lattice monotonicallyincreased with temperature, however, in addition to this, the release of distortion from the Jahn-Teller effect of Mn3+ ion
occurred over a wide temperature range, which brought the negative expansion of the a- axis, although the b- andc-axes increased with temperature. The anomalous thermal expansion is explained by the sum of the effects of theshrinkage of the a-axis and absorption of the b- and c-axes' expansion by the pores in the sintered body.

Imanishi, K. Shizuka*, T. Ikenishi, T. Matsumura, A. Hirano and Y. Takeda : Solid State Ionics 177, pp. 1341-1346,
2006
Solid solution materials of Li2CuO2 and Li2NiO2 were studied with respect to their electrochemical performanceand crystal structure. The Li2CuO2–Li2NiO2 system shows a solid solution over the whole composition range with theorthorhombic structure. Pure Li2CuO2 has a reversible capacity of only 100 mA h/g, and the capacity of Li2Cu1−xNixO2
increased with increasing the content of Ni. The maximum capacity of 250 mA h/g is obtained for Li2Cu0.5Ni0.5O2, andit exhibits a good reversibility for charge and discharge cycles. The orthorhombic Li2CuO2 undergoes a phase change tothe monoclinic LiCuO2 during lithium deintercalation, while nickel-rich compositions show a new phase that isdifferent from either the original orthorhombic or monoclinic structure.

Ionics 177, pp. 2165-2173, 2006
TEM observation and electron diffraction analysis of a laser ablation perovskite film was carried out. The film
was deposited on a single-crystal substrate and showed epitaxial growth normal to the substrate. The crystal orientationof the perovskite film varies depending on the kind of single-crystal substrate. The surface structure of the atomic
arrangement was investigated based on an analysis of electron diffraction patterns. Its relation to the kinetics of the
reduction of molecular oxygen is discussed.

Novel Composite Anodes Consisting of Lithium Transition-Metal Nitrides and Transition Metal Oxides for
Rechargeable Li-Ion Batteries, Y. Liu, Y. Takeda, T. Matsumura, J. Yang*, N. Imanishi, A. Hirano, and O. Yamamoto* :J. Electrochem. Soc., 153 (2 ) , pp. A437-A444 , 2006
Lithium transition-metal nitrides are promising anode candidates for Li-ion batteries. However, lithium must be
extracted from the nitrides in an initial anodic oxidation, indicating these compounds cannot directly combine with thecurrent cathodes to constitute cells. This deterrent can be overcome by introducing a certain amount of Co3O4, whichshows large capacities and relatively high oxidation/reduction potentials, into the electrodes containing the above
nitrides. A thermodynamically spontaneous reaction between these two active hosts results in a delithiated state oflithium metal nitrides. Under cycling within 1.4–0 V vs Li/Li+, Co3O4 is relatively inert to lithium and the nitrides
become electrochemically active. The composite electrodes show high first-cycle efficiency of 100%, large capacities of
500 mAh g–1, and excellent cyclability. Furthermore, research revealed that the composite electrodes demonstrated
high cycling stability operating with polyethylene oxide (PEO) electrolytes at the elevated temperature. The reaction
heating of the composite electrode under high Li utilization with PEO electrolytes via differential scanning calorimetry
measurement was found to be extremely low compared with those of the lithium metal and the Li-alloy-based systems,suggesting that the composite electrodes could be promising anode candidates for all-solid-state PEO Li-ion batteries interms of capacity, first-cycle charge efficiency, and thermal reliance.

A―37

NaxFeO2 was obtained by chemical oxidization method using NO2BF4 and Br2 which shows the redox potentialof ca. 5.1 V and ca. 4.1 V vs Li / Li+ , respectively. The oxidized products showed different X-ray diffraction patterns
depending on the oxidizing species. In case of NO2BF4 , as soaking time progressed, new phase increased withdecreasing of NaFeO2 as stating material. The oxidized NaxFeO2 was possible to be inserted the Li ion
electrochemically, and resulted in the crystal structure similar to the layered LiFeO2 synthesized by the Li-ion-exchange
method from NaFeO2. Reversible discharge-charge reactions were progressed for NaxFeO2// Li cell, and ac.150 – 200
mAh/g of initial capacities were achieved although the capacities decreased with cycle numbers.
