Photochemical reaction mechanisms of 4,5-dimethoxy-2-nitrobenzyl acetate analysed by a sub-10 fs near-ultraviolet pulse laser
Sena Hashimoto, Kenta Hamada, Izumi Iwakura*, Atsushi Yabushita, Takayoshi Kobayashi, Hirotaka Fujita, Kento Takeda, Yuta Ono, Noriko Chikaraishi Kasuga, Kazuo Yamaguchi
Chemical Physics   524 70-76   Aug 2019   [Refereed]
The present study examined the electronic dynamics of 4,5-dimethoxy-2-nitrobenzyl acetate after π-π* excitation. Pump-probe measurement using a near-ultraviolet sub-10 fs pulse laser revealed that the lifetime of the S*(π- π*) state is ...

Chemical Physics   512 128-134   Aug 2018   [Refereed]
Photoexcitation of 9,9'-bianthryl has been considered to produce a locally excited (LE) state and then a charge transfer (CT) state by intramolecular charge transfer (ICT) in polar solvents. In contrast, the CT state is considered to be...
Transient process spectroscopy for the direct observation of inter-molecular photo-dissociation
Sena Hashimoto, Atsushi Yabushita, Izumi Iwakura*
Structural Dynamics   4 054901   Sep 2017   [Refereed]
Transient process spectroscopy has previously been thought to be applicable only to the analysis of intra-molecular processes. Two metal ion bridges used in the present work have allowed us to visualize real-time variations of the molecular vibrat...
Real-time observation of interfragment vibration and charge transfer within the TCNQF4 dimer
Sena Hashimoto, Atsushi Yabushita, Izumi Iwakura*
Chemical Physics   493 56-60   Aug 2017   [Refereed]
The organic electron acceptors, TCNQ and TCNQF4, are widely used to synthesize multivalent CT complexes. Their corresponding radical anion complexes have specific electronic, optical, and magnetic characters that have attracted attentio...
Pulsed Nd:YAG Laser-induced Photoreaction of cis,cis-1,3-Cyclooctadiene at 266 nm: Selective Cyclization to cis-Bicyclo[4.2.0]oct-7-ene
Keiko Komori-Orisaku, Yui Hirose, Izumi Iwakura*
Photochemical & Photobiological Sciences   16 146-150   Feb 2017   [Refereed]
Nanosecond-scale pulsed laser irradiation of cis,cis-1,3-cyclooctadiene via an Nd:YAG laser at 266 nm induced highly selective cyclization of the 1,3-diene moiety to afford cis-bicyclo[4.2.0]oct- 7-ene in high yield. The pulsed Nd:YA...
