Three PTRI Research Seminars will be conducted by visiting professors from Osaka University, discussing varied topics.
New Chelation-Assisted Transformations of C-H Bonds Utilizing Bidentate Directing Groups, Professor Naoto Chatani, Department of Applied Chemistry
Chelation-assistance is now one of more reliable methods for transforming C-H bonds. These reactions permit the highly regioselective transformation of C-H bonds proximal to a coordinating functional group into a new C-X bond. A wide variety of functional groups has been evaluated as directing groups to date in the transformation of C-H bonds. However, in spite of the tremendous progress made to date, the development of new types of directing groups continues to be important, in terms of exploring novel types of transformations of C-H bonds that cannot be achieved by conventional directing groups.
The talk will focus on some new transformations of C-H bonds by taking advantage of N,N-bidentate directing groups, such as 2-pyridynylmethylamine and 8-aminoquinoline in the presence of transition metal complexes.
Genetic Engineering of Daphnia magna, Professor Hajime Watanabe, Department of Biotechnology
The waterflea Daphnia magna has been used as the subject of the ecology, evolution and environmental sciences for decades. While the Daphnia genome project accelerated our understanding of daphnid biology at molecular levels, understanding of gene functions was still a great problem. In order to clarify gene functions of daphnia, we are developing genetic engineering technology on Daphnia magna. Combined with DNA microarray technique, which we previously developed, this technology will help us to understand daphnid biology and contribute to evolutional, ecological, environmental and molecular biology.
Non-contact Conductivity Measurement in Semiconductor Materials, Professor Shu Seki, Department of Applied Chemistry
Charge carrier mobility is an essential parameter providing control over the performance of semiconductor devices fabricated using a variety of organic molecular materials.
The present paper highlights the evaluation methodologies of charge carrier mobility in organic materials, as well as the merits and demerits of techniques examining the feasibility of organic molecules, crystals, and supramolecular assemblies in semiconductor applications. Beyond the simple substitution of amorphous silicon, we have attempted to address in this perspective the systematic use of measurement techniques for future development of organic molecular semiconductors.
