Abstract
An indolylfulgide having a 1-(1,2-dimethyl-3-indolyl)-2,2,2-trifluoroethylidene group on the succinic anhydride showed an excellent resistivity towards the repetition of photochromic transformation between the photostationary states of UV- and visible-light irradiation both in toluene and in a PMMA film under the atmospheric environment. The colored form also showed the remarkable thermal stability.

Abstract
Slab optical waveguide (SOWG) was employed for obtaining absorption spectra of rhodamine 6G (Rh6G) with the concentration of 1 μmol/dm3. It was found that Rh6G existed as a monomer and dimer on SOWG surfaces. On the SOWG surfaces treated with octadecylsilane only the band assigned to a monomer of Rh6G was observed.

Published: March 2006

Abstract
The interaction of the chemically synthesized DNA-binding protein J (SynJ) of bacteriophage φK with its single stranded circular φK DNA (css-DNA) was examined by circular dichroism and fluorescence methods. A strong cooperative binding between the synJ and the css-DNA was observed in 20 mmol dm−3 Tris-HCl buffer (pH 7.3) with 200 mM NaCl. While an electrostatic simple binding was observed in the buffer without NaCl.
Kinetic Determination of Organic Vapor Mixtures with Single Piezoelectric Quartz Crystal Sensor Using Artificial Neural Networks and Partial Least Squares
Authors: Xing Wan-Li , He Xi-Wen 
Published: March 2006

Abstract
A single piezoelectric quartz crystal coated with one kind of crown ether was applied to the simultaneous determination of acid and amine vapor mixtures. From the adsorption and desorption curves of analytes, which had somewhat differences in shape, frequency shifts from ten time windows were taken as inputs for two chemometric methods, partial least squares (PLS) and artificial neural networks (ANN). The results showed that the perdiction was better for artificial neural networks in both sample sets.

Authors: Houjou Hirohiko , Sakurai Minoru , Inoue Yoshio 
Published: March 2006

Abstract
Dielectric medium effects on absorption maxima of protonated retinal Schiff bases (PSB) are studied using a reaction field theory incorporated into the INDO/S method. The calculation shows that a counterion, such as carboxylate, has no explicit role in regulating the absorption maximum of PSB even in a low dielectric medium.
Facile Synthesis of the 1,3-Disilacyclohexane Ring
Authors: Mizuno Katsuya , Inamasu Naoko , Shimizu Masaki , Hiyama Tamejiro 
Published: March 2006

Abstract
A new method for the synthesis of the 1,3-disilacyclohexane skeleton is established involving silylation of a dithioacetal followed by ring closure with a base. The spiro-fused disilacyclohexane ring is shown to be structurally strain-free, like cyclohexane, on the basis of its X-ray analysis. The reaction mechanism involving a silacyclopropane intermediate is proposed.

Published: March 2006

Abstract
Time-resolved infrared studies of intermediates generated by photolysis of the title azide in solution at room temperature demonstrated that 3-(methoxycarbonyl)azacycloheptatetraene was the sole intermediate at least in the μs time scale, which is in sharp contrast with that observed in the photolysis in argon matrix at 10 K. Substituent effects on the reactivity of the dehydroazepine toward diethylamine are also discussed.

Mechanism of Electron Transfer Oxidation of 4-Substituted 1-Benzyl-1,4-dihydronicotinamides
Authors: Takada Naoki , Itoh Shinobu , Fukuzumi Shunichi 
Published: March 2006

Abstract
Electron transfer oxidation of variously 4-substituted 1-benzyl-1,4-dihydronicotinamides (RBNAH) by [Fe(phen)3]3+ (phen = 1,10-phenanthroline) results in formation of RBNAH•+, followed by cleavage of the C(4)-H or C(4)-C bond of RBNAH•+ depending on the substituent R. In particular, the C(4)-C bond cleavage of t-BuBNAH•+ yields exclusively BNA+ and tert-butylradical (t-Bu•) which is detected by applying a rapid mixing flow electron spin resonance (ESR) technique.

Published: March 2006

Abstract
In the gas-solid heterogeneous reactions of particle-supported fluoranthene with ppm levels of nitrogen dioxide and ozone, dinitrofluoranthenes and 3-nitrofluoranthene (3-NF) were formed only in the dark and 2-NF was formed only under photoirradiation while 1-, 7-, and 8-NFs were formed under both conditions. Yield and distribution of the products varied depending on the kind of supports employed.

Authors: Nimura Shigeaki , Kikuchi Osamu , Ohana Tsuguyori , Yabe Akira , Kaise Masahiro 
Published: March 2006

Abstract
Singlet-triplet energy gaps of phenylene-1,4-dinitrene (1), biphenyl-4,4′-dinitrene (2), stilbene-4,4′-dinitrene (3), and azobenzene-4,4′-dinitrene (4) were determined from temperature dependence of ESR signal intensities. These quinonoidal dinitrenes show interesting features: (1) the energy gap of 1 is comparable to that of 2, and (2) the gap of 4 is almost one-half of the gap of 3. The results are qualitatively explained by magnitudes of polarized π spins.
Structure and Catalysis of a SiO2-Supported Gold-Platinum Cluster [(PPh3)Pt(PPh3Au)6](NO3)2
Authors: Yuan Youzhu , Asakura Kiyotaka , Wan Huilin , Tsai Khirui , Iwasawa Yasuhiro 
Published: March 2006

Abstract
A novel catalyst of [(PPh3)Pt(AuPPh3)6](NO3)2 1 supported on SiO2 was very active in H2-D2 equilibration with a TOF of 29.8 s−1, while it showed low activity for ethene hydrogenation and CO oxidation at 303 K. It was found that the catalysis of 1/SiO2 was not caused by platinum particle impurity but by the platinum atom which bound to the gold atoms in the cluster. The cluster framework of 1/SiO2 was stable during the reactions at 303 K. The change of Au-Pt bond in 1/SiO2 by heat treatment and the catalytic performance of produced cluster fragments were characterized by EXAFS, FT-IR and kinetic investigation.

Authors: Yin Ming , Kuwabara Tetsuo , Nanasawa Masato 
Published: March 2006

Abstract
A multi-process model consisting of a distribution of rate constant of each process was proposed to explain the thermal decoloration of the colored species of 4-hexadecyl-4′-methoxysalicylideneaniline in polycarbonate matrix. The kinetic equation deduced from this model indicates that the lifetime of the colored species linearly increases with time for the decoloration in heterogeneous matrix.

Published: March 2006

Abstract
Extremely stable carbocations, tris(6-methoxy-1-azulenyl)methyl, bis(6-methoxy-1-azulenyl)(4-methoxyphenyl)methyl, and (6-methoxy-1-azulenyl)bis(4-methoxyphenyl)methyl cations were prepared and their pKR+ values were determined spectrophotometrically as &gt;14.0, &gt;14.0, and 13.2, respectively. The extreme stability of these methyl cations are attributable to dipolar structures of azulene rings in addition to the contribution of mesomeric effect of three methoxy groups.

The First Example of Enantioselective Protonation of Prochiral Enolates with Chiral γ-Hydroxyselenoxides
Authors: Takahashi Tamiko , Nakao Naoki , Koizumi Toru 
Published: March 2006

Abstract
Enantioselective protonation of a simple enolate has been developed using an optically pure γ-hydroxyselenoxide 1 as a chiral proton source. Reaction of zinc bromide enolate 7b with (SSe)-selenoxide (SSe)-1c gave (S)-2-benzylcyclohexanone (S)-8 with high enantioselectivity. Intramolecular hydrogen bonding between hydroxy group and seleninyl-oxygen of 1 would contribute to this asymmetric induction.
Photoluminescence Characteristics of Calcined Silica Gels Containing Carbonized Intermediates
Authors: Yamada Nobusuke , Sano Masahito , Yoshimura Susumu 
Published: March 2006

Abstract
Photoluminescence was observed from the carbonization intermediates of acenaphthylene or 2-methyl-1,2′-naphthyl ketone in silica gels by an excitation wavelength of 337 nm. As the calcination temperature incresed from 500 to 1000 °C, the spectral line shape exhibiting two regions of maxima centered at 390 and 490 nm changed systematically. No photoluminescence was seen from the samples without calcination, nor from a clear gel calcined over 1050 °C. SEM observations indicate uniform mixing of the intermediates in the silica matrix down to a few tens of nanometers.
