Journal ArticleDOI
Coherent singlet fission activated by symmetry breaking
Kiyoshi Miyata,Yuki Kurashige,Yuki Kurashige,Kazuya Watanabe,Toshiki Sugimoto,Toshiki Sugimoto,Shota Takahashi,Shunsuke Tanaka,Jun Takeya,Takeshi Yanai,Yoshiyasu Matsumoto +10 more
TL;DR: Ultrafast spectroscopic measurements and quantum chemical calculations have now uncovered aspects of the process critical to it occurring efficiently, including the role of intermolecular vibrations and symmetry breaking, and the location of a conical intersection on the excited-state potential-energy surface.
Journal ArticleDOI
Conformational Planarization versus Singlet Fission: Distinct Excited-State Dynamics of Cyclooctatetraene-Fused Acene Dimers
Takuya Yamakado,Shota Takahashi,Kazuya Watanabe,Yoshiyasu Matsumoto,Atsuhiro Osuka,Shohei Saito,Shohei Saito +6 more
TL;DR: A set of flapping acene dimers fused with an 8π cyclooctatetraene ring showed distinct excited-state dynamics in solution, demonstrating the utility of the flapping molecular series as a versatile platform for designing photofunctional systems.
Journal ArticleDOI
Water-Assisted Hole Trapping at the Highly Curved Surface of Nano-TiO2 Photocatalyst
Kenji Shirai,Gianluca Fazio,Toshiki Sugimoto,Toshiki Sugimoto,Daniele Selli,Lorenzo Ferraro,Kazuya Watanabe,Mitsutaka Haruta,Bunsho Ohtani,Hiroki Kurata,Cristiana Di Valentin,Yoshiyasu Matsumoto +11 more
TL;DR: It is clarified that water enhances hole trapping at the surface of TiO2 nanospheres but not of well-faceted nanoparticles, which provides a novel and rational basis for designing and engineering nanophotocatalyst morphology to improve photocatalytic performances.
Journal ArticleDOI
Formation of alkanethiolate-protected gold clusters with unprecedented core sizes in the thiolation of polymer-stabilized gold clusters
Hironori Tsunoyama,Patricia Nickut,Yuichi Negishi,Katharina Al-Shamery,Yoshiyasu Matsumoto,Tatsuya Tsukuda +5 more
TL;DR: In this paper, the authors show that the Au:SR (R = organic group) clusters with a high tolerance to thiol etching can be systematically synthesized by first populating precursory Au clusters in a poly(N-vinyl-2-pyrrolidone) matrix with subsequent thiolation of the preformed Au clusters.
Journal ArticleDOI
Intersystem crossing in isolated molecules. Magnetic field effects on the fluorescence decay behavior of 1B3u pyrazine with ‘‘single’’ rovibronic level excitation
TL;DR: In this article, it was shown that complete spin decoupling from the molecular frame, leading to the intersystem crossing (ISC) selection rule ΔJ=0,±1, occurs at the anomalously low field of ∼100 G.
