Reconstruction of Au(111) Following the Reductive Desorption of Self-Assembled Monolayers of 2-Mercaptoethanesulfonic Acid Studied by in Situ Scanning Tunneling Microscopy
Authors: Hobara Daisuke , Yamamoto Masahiro , Kakiuchi Takashi 
Published: September 2002

Abstract
The reconstruction of Au(111) to (√3 × 23) structure after the reductive desorption of a self-assembled monolayer (SAM) composed of 2-mercaptoethanesulfonic acid (MESA) has been imaged by in situ scanning tunneling microscopy (STM) in a 0.5 mol dm−3 KOH aqueous solution. The STM images clearly show that after the reductive desorption of MESA the Au(111) surface reconstructs to the (√3 × 23) structure. The reconstruction starts from the edge, spreads gradually, and covers the entire terraces of Au(111) on the time scale of several minutes. Pits of the gold substrate are formed especially at the boundaries between the unreconstructed and the reconstructed areas during the spread of the reconstruction.

The First Chemical Trapping of Stibinidene, a Monovalent Antimony Compound
Authors: Sasamori Takahiro , Arai Yoshimitsu , Takeda Nobuhiro , Okazaki Renji , Tokitoh Norihiro 
Published: September 2002

Abstract
Deselenation of a 1,3,5-triselena-2,4,6-tristibane bearing 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl (denoted as Tbt) groups in the presence of 1,3-butadienes resulted in the formation of the corresponding [1 + 4]-cycloadducts of a sterically hindered stibinidene (Tbt-Sb:), a monovalent species of antimony. Thermal generation of the stibinidene from the stibolene derivatives via retro [1 + 4]-cycloaddition reaction was suggested by the diene-exchange reaction in thermolysis of the adducts in the presence of another butadiene derivative.

Hyper-Rayleigh Scattering of CdS Nanoparticles with Different Surfaces
Authors: Zhang Yu , Wang Xin , Fu Degang , Liu Juzheng , Cui Yiping , Lu Zuhong 
Published: September 2002

Abstract
The first-order hyperpolarizability β values of two kinds of CdS nanoparticles with different surfaces were experimentally determined in solution via an incoherent hyper-Rayleigh scattering (HRS) technique. It is found that the β value of CdS nanoparticles capped with 2, 2′-bipyridine is 4.27 × 10−27 esu which is about a factor of 3 smaller than the β value (1.30 × 10−26 esu) of bare CdS nanoparticles whose surface is not modified by organic groups. This difference is interpreted in terms of a two-level model approximation derived from molecular chromophores, when considering the contribution of molecule-like scatterers at the particle surfaces.

Published: September 2002

Abstract
The crystal structures and magnetic properties of two-dimensional coordination polymers [M(tdpd)(H2O)2]n (M = Mn2+ and Co2+) involving the triangular lattice are determined. The magnetic behaviors of 1 and 2 may come from the single-ion behavior and the specific arrangement of the metal ions.
A Novel Change of Light Transmission in Supercooled Liquid State of Ethylbenzene
Authors: Ishii Kikujiro , Okamura Takahiro , Ishikawa Nami , Nakayama Hideyuki 
Published: September 2002

Abstract
By the continuous elevation of temperature, ethylbenzene in the supercooled liquid state first turns opaque and then becomes transparent again before it finally crystallizes. These observations are possibly related to the appearance of the second amorphous state with a correlated structure that has recently been reported for triphenyl phosphite.

Abstract
The crystal structure determination of tris(vanadyl)-substituted tungstoantimonate(III) K11H[(VO)3(SbW9O33)2]·27H2O reveals that the [(VO)3(SbW9O33)2]12− anion contains three exterior VO2+ groups sandwiched by two α-B [SbW9O33]9− ligands in VIV···VIV separation of 5.411(8)-5.464(8) Å and is stabilized by equatorial three K+ ions triangle with virtual D3h symmetry. An observable spin-exchange interaction between VIV centers within the vanadyl coplanar triangle is demonstrated in terms of S = 1/2 and S = 3/2 states.

Authors: Karuppuchamy Subbian , Amalnerkar Dinesh P , Yamaguchi Koichi , Yoshida Tsukasa , Sugiura Takashi , Minoura Hideki 
Published: September 2002

Abstract
A convenient – and quick to realize – approach for cathodic electrodeposition of TiO2 films is suggested. Scanning electron microscopic examination of the resultant films reveals the formation of mesoporous TiO2. Since dye-sensitized photoelectrochemical investigations on cathodically electrodeposited TiO2 films are hitherto unreported, we performed such investigations by sensitizing our mesoporous TiO2 films with cis-bis(4,4′-dicarboxy-2,2′-bipyridine)bis(thiocyanato)ruthenium(II). The preliminary studies exhibit incident photon-to-current conversion efficiency (IPCE) above 35% in the first attempt.

Authors: Hirano Keisuke , Minakata Satoshi , Komatsu Mitsuo 
Published: September 2002

Abstract
Novel fluorophores, 3,4,6-triphenyl-α-pyrone derivatives, were synthesized and their spectroscopic properties have been investigated. In the solid state they show intense greenish-yellow fluorescence, but not in solution. It is concluded that the 6-phenyl group is fixed at an angle of about 26° to the pyrone plane in the solid state by molecular packing and this fixation is required for this unique fluorescent property.
Orthorhombic LiMnO2 as a High Capacity Cathode for Lithium-Ion Battery Synthesized by Hydrothermal Route at 170 °C
Authors: Myung Seung-Taek , Komaba Shinichi , Kumagai Naoaki 
Published: September 2002

Abstract
An orthorhombic LiMnO2 having a high capacity was hydrothermally synthesized at 170 °C from Mn3O4 obtained through autoxidation route. The LiMnO2/Li cell demonstrated the initial reversible capacities of about 210 mAh (g-oxide)−1 at 30 °C. After several initial cycling, the cell showed stabilized cycling behavior (175 mAh g−1 at the 30th cycle). We believe that orthorhombic LiMnO2 prepared by a new hydrothermal condition is an excellent candidate for the cathode of coming generation of high capacity material to be applied for lithium-ion secondary battery.
Generation and Behavior of 9-Anthroyloxyl Radicals in Photocleavage of N-(9-Anthroyloxy)-9-fluorenylideneamine
Authors: Saitoh Yasuo , Kaneko Makoto , Segawa Katsunori , Itoh Hiroki , Sakuragi Hirochika 
Published: September 2002

Abstract
9-Anthroyloxyl radicals are generated from photocleavage of the N-O bond of N-(9-anthroyloxy)-9-fluorenylideneamine and 1-(9-anthroyloxy)-2-pyridone in acetonitrile. They are much less reactive in decarboxylation, addition to olefins, and hydrogen-atom abstraction than benzoyloxyl and 1-naphthoyloxyl radicals, and supposedly undergo intramolecular addition to the ipso position to give α-lactonic spiroanthracenyl radicals.
