报告介绍

报告摘要:

  One of the problems of conventional photoswitches is in the use of UV light as the trigger of the switch in at least one direction. Due to the harmful reactions and high absorption of UV light at the surface, it is preferable to use visible or IR light for controlling a photoswitch. We theoretically investigated the mechanism of a switch of one of such photoswitching organic molecules, a fluorescent dye attached diarylethene. We show the photoswitching reaction upon irradiation with green light occurs due to multiplicity conversion based on intramolecular energy transfer from the excited singlet state of the fluorescent dye to the triplet state of diarylethene.


报告人简介:

  Satoshi Yokojima studied field theory in physics at Keio University. He received PhD in 1995 supervised by Prof. R. Fukuda. He then worked on optical response with Prof. S. Mukamel at University of Rochester. He moved to The University of Hong Kong and developed a linear scaling method with Prof. G.H. Chen. After working with Prof. Y.J. Yan on dissipative systems, he studied a charge transfer in DNA with Dr. A. Okada at University of Tsukuba. He joined Dr. S. Nakamura’s group at Mitsubishi Chemical and worked on photochromic systems. He moved to Tokyo University of Pharmacy and Life Science in 2011 and promoted to Professor in 2016.
