The main photolytic products by far-uv were 5,6-dihydrothymine (DHT) (selectivity: S (DHT) = 0.2) and 5-hydroxymethyluracil (HMU) (S(HMU) = 0.1) under N2-saturated conditions, cis- and trans-5,6-Dihydroxy-5,6-dihydrothymine (TG), 6(5)-hydroperoxy-5(6)-hydroxy-5,6-dihydrothymine (HTP) (S(TG) + S (HTP) = 0.2), and N1 -formyl-N2-pyruvylurea (FPU) (S(FPU) = 0.4) were obtained under aerated conditions. These products were attributed to the reactions of thymine with the H and OH produced by photolysis of water.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ THY・1986 (full paper)　《3》 OTHERS［received 1986/01/02］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Ohtani, B.</B>; Nagasaki, H.; Nishimoto, S.-i.; Kagiya, T., Far Ultraviolet Induced Decomposition of Thymine in Deaerated and Aerated Aqueous Solutions, <I>Can.

The oxygen (O2) uptake proceeded slowly in the absence of sensitizers upon irradiation of an aqueous emulsion and an acetonitrile solution of ML‐H (20 mM) at λex &gt; 290 nm (11.4 and 6.1 μmol h‐1, respectively). The rate of O2 uptake was enhanced by a catalytic amount (0.1 mM) of porphyrins and dyes; hematoporphyrin (HP), zinc tetrakis(N‐methyl‐4‐pyridiniumyi)porphyrin (ZnTMPyP), methylene blue (MB), rose bengal (RB), acridine orange (AO), and acriflavine (AF). In both systems, the sensitized photooxidation of ML‐H by O2 proceeded equimolarly to produce isomeric mixture of C9 and C13 hydroperoxides having the trans,cis and trans,trans conjugated diene configurations, independent of the types of the sensitizers used. The yield ratio of trans,trans/ trans,cis products in the MB‐sensitized photooxygenation in acetonitrile and aqueous emulsion were almost equal (0.32 and 0.35. respectively). The sensitizing activity of the sensitizers, as measured by the quantum yield of O2 uptake, increased in the order: MB (〜 0) &lt; ZnTMPyP &lt; RB &lt; HP &lt; AF &lt; AO in the aqueous emulsion and AO &lt; AF &lt; HP &lt; RB = MB in the acetonitrile solution. The order in homogeneous acetonitrile solution was interpreted by the sensitizing ability of the dyes to produce singlet oxygen, while that in heterogeneous aqueous emulsion was correlated to the lipophilicity of dyes as well as the singlet‐oxygen‐producing ability.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ MLH・1986 (full paper)　《14》 OTHERS［published online 2008/01/02］</FONT> </SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Ohtani, B.</B>; Nishida, M.; Nishimoto, S.-i.; Kagiya, T.*, Photooxygenation of Methyl Linoleate Sensitized by Porphyrins and Dyes in Acetonitrile Solution and Aqueous Emulsion Systems, <I>Photochem.

The light-intensity dependence of both flake ball-shaped micrometer-sized particles (FB-BWO) and wet ball-milled nanometer-sized particles (ML-BWO) seemed to be bimodal, i.e., first and 0.5th orders in the lower and higher intensity ranges, respectively. Approximately 1.5th and second-order light-intensity dependences were also observed for ML-BWO at the lowest intensity range and for FB at the highest intensity range, respectively. The light-intensity dependences could be reproduced by a kinetic model that was derived on the basis of the assumption of oxygen reduction via two-electron (and possibly four-electron at the highest intensity region) transfer and a radical chain mechanism with peroxy radicals as chain carriers. The calculated threshold intensity between the first and 0.5th-order light-intensity dependences for FB-BWO was appreciably lower than that of ML-BWO, suggesting that the higher FB-BWO activity is attributable to the larger effective particle size for accumulation of two (or four) electrons.'><TR BGCOLOR=#663333><TD COLSPAN= VALIGN=middle popup_e> <SPAN CLASS=large><FONT COLOR=white><A NAME=''></A>■ BTKNF・2018 (full paper)　《9》 MULTIE［accepted 2018/01/02］</FONT> <IMG SRC='/image/misc/huscap.png' HEIGHT=15 VARIGN=bottom></SPAN></TD></TR><TR><TD VALIGN=middle BGCOLOR=#FFFFDD><B>Hori, H.</B>; <B>Takashima, M.</B>*; <B>Takase, M.</B>; <B>Ohtani, B.</B>, Kinetic analysis supporting multielectron reduction of oxygen in bismuth tungstate-photocatalyzed oxidation of organic compounds, <I>Catal.
