Stepwise Two-Photon Absorption Processes Utilizing Photochromic Reactions
Publication date: Available online 25 December 2017 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Yoichi Kobayashi, Katsuya Mutoh, Jiro Abe Stepwise two-photon absorption (2PA) is one of the nonlinear photoresponses where two photons are sequentially absorbed to proceed a photophysical or photochemical reaction. The stepwise 2PA can selectively produce a higher excited state with relatively high spatial selectivity, and therefore, it can be an efficient tool to explore and realize nonlinear photoresponsive materials beyond Kasha’s rule. Moreover, if a photogenerated chemical ...

Chirality and Stereoselectivity in Photochromic Reactions
Publication date: Available online 21 December 2017 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Tetsuya Nakagawa, Takashi Ubukata, Yasushi Yokoyama In this review, the chirality and stereoselectivity in photochromic reactions are broadly discussed. Stereoselectivity is categorized into the two main areas of enantioselectivity and diastereoselectivity. Enantioselective photochromism was discussed according to the methods of generating chirality, that is: (1) optical resolution of chiral and racemic compounds, (2) spontaneous separation of racemic compounds during crystallizati...

Reaction dynamics of excited radical ions revealed by femtosecond laser flash photolysis
Publication date: Available online 16 December 2017 Source:Journal of Photochemistry and Photobiology C: Photochemistry Reviews Author(s): Mamoru Fujitsuka, Tetsuro Majima Herein, we review studies on the dynamics of excited radical ions. The enhanced reactivities of excited radical ions are recognized by many researchers based on product analysis studies conducted around 1980. For cases involving fluorescent excited radical ions, lifetime measurements provide information on excited states, and they sometimes lead to confusion owing to emissive byproducts resulting from their higher reactivities. Nanosecond laser flash...
