Mukaiyama. Following an initial period as assistant professor, he was promoted to lecturer then associate professor at Science University of Tokyo (SUT). In 1998, he moved to the Graduate School of Pharmaceutical Sciences, the University of Tokyo, as full professor. In 2007, he was appointed to his current position as professor of Organic Chemistry in the Department of Chemistry, Faculty of Science, the University of Tokyo. He has held various visiting professorships, including the Universite Louis Pasteur, Strasbourg (1993), Kyoto University (1995), Nijmegen University (1996), Philipps-University of Marburg (1997), Paris-Sud (2010). Professor Kobayashi has wide-ranging research interests that include the development of new synthetic methods and novel catalysts, organic reactions in water, solid-phase synthesis, total synthesis of biologically interesting compounds, and organometallic chemistry. He has held numerous named lectureships and is a recipient of many prestigious awards, including the Chemical Society of Japan Award for Young Chemists (1991), Springer Award in Organometallic Chemistry (1997), IBM Science Award (2001), Organic Reactions Lecturer (2002), Nagoya Silver Medal (2002), Mitsui Chemical Catalysis Science Award (2005), JSPS Prize (2005), the Arthur C. Cope Scholar Award from the American Chemical Society (2006), Howard Memorial Lecturer (2006), C.S. Hamilton Award (2007), Merck-Cambridge Lecturer (2007), Humboldt Research Award (2013), and Green Chemistry Minister of Education Award (2013). 2 Immobilized Catalysts for Green Sustainable Chemistry Shū Kobayashi Department of Chemistry, School of Science, The University of Tokyo Hongo, Bunkyo-ku, Tokyo 113-0033 Japan E-mail: [email protected] Abstract Homogeneous catalysts and heterogeneous catalysts have merits and demerits that are somehow conflict. “Dream catalysts” have both merits, and in this lecture our trials to develop “dream catalysts” are described. Several types of metal nanoclusters as immobilized catalysts for reduction, oxidation, and C-C bond-forming reactions including asymmetric catalysis will be discussed. For example, we have developed heterogeneous polymer-incarcerated nickel nanoparticles, which catalyzed cross-coupling reactions. The matrix structure of these catalysts incorporates both N-heterocycle carbenes as ligands and nickel nanoparticles, thanks to a new design of cross-linking agents in polymer supports. These embedded NHCs were detected by Field Gradient Swollen-Resin Magic Angle Spinning (FG-SRMAS) NMR analysis. They were successfully applied to Corriu– Kumada–Tamao reactions with a broad substrate scope including functional group tolerance, and the catalyst could be recovered and reused several times without loss of activity.

He received B.S. (1977) and M.S. (1979) degrees from Kumamoto University under the direction of Prof. Kimiho Yamada in Synthetic Chemistry. He received a Ph.D. (1982) from Kyushu University under the direction of Prof. Toyoki Kunitake in Polymer Chemistry. He became Professor in Kumamoto University (1997). He is now the leader of the Supramolecular Chemistry Group at the Department of Applied Chemistry and Biochemistry, Kumamoto University as well as Vice President of Kumamoto University for International Affairs. Keywords for current research fields: molecular assembling for supramolecular chemistry; nano-architecture based on highly-ordered systems; functional molecular gels; photo-electro organics, and so on. His achievements have been reported as 300 journal papers and 100 patents. 4 Supramolecular Gels Hirotaka IHARA Department of Applied Chemistry and Biochemistry, Kumamoto University, Japan Kumamoto Institute for Photo-Electro Organics, Japan E-mail: [email protected] URL: http://www.chem.kumamoto-u.ac.jp/~iahra/ Abstract Gels are generally defined as a dilute cross-linked system, which exhibits no flow but mostly composed of a liquid. Therefore, a gel state is often observed by chemical crosslinking of well-dispersed amorphous polymers to produce three dimensional network. On the other hand, our gels1 are absolutely different from these conventional gels because the gel state can be achieved by fibrillar aggregation of low-molecular-weight compounds but not polymers, and therefore the resultant gels show supramolecular functions through formation of highly-ordered secondary structures. This paper introduces our basic idea to create supramolecular gels and some applications. Some of our successful examples are found in peptide-based derivatives. For example, a lipophilic L-glutamide derivative, which is prepared by introduction of a chromophoric group and two long chain alkyl groups via amide bonds into L-glutamic acid, behaves as a gelator in organic solvents such as benzene, toluene and cyclohexane. TEM and SEM observation indicate that the L-glutamide forms nano-fibrillar aggregates and the gelation can be brought about by three-dimensional network formation. This paper also demonstrates that the obtained nano-fibrillar aggregates show unique optical properties in CD and fluorescent spectra when pyrene is selected as a chromophoric group.2-4 For example, an excimeric fluoresce can be observed in gel-forming solvents but not in the others. This is due to high molecular ordering among pyrene moieties, and as a result high Stokes shift is realized. This phenomenon is fortunately performed even in polymer films such as polystyrene and PMMA.5-7 In this paper, we also demonstrate the application as a light-management film for power conversion enhancement of solar cells. The enhancement of power conversion efficiency can be due to high Stokes shift realizing the wavelength conversion from UV-A to useful visible light. 1. H. Ihara, M. Takafuji, T.
