Halochromism of 2-Indolinone Fluorophore Based on the Deprotonation of an Acidic C–H Bond

Chemistry Letters (2024)

Naoya Suzuki Keita Yagi Takeshi Maeda Shintaro Kodama Shigeyuki Yagi

Abstract We disclosed a new halochromic fluorescent dye based on the deprotonation from an acidic C–H bond. The dye consisting of a 2-indolinone skeleton and a benzothiazole ring exhibited an obvious red shift in its photoluminescence spectra in response to the presence of bases. Structural analyses with 1H NMR measurements and theoretical calculations suggested that the π-conjugated system of the dye was expanded by the deprotonation of the acidic C–H bond on the 2-indolinone skeleton. This structural change contributes to the red shift of photoluminescence and accelerates the radiative decay from the excited state.

Characteristics of Ti-MCM-41 Post-synthesized in Organic or Aqueous Solution using Organo-titanium Compounds as Ti Sources

International Journal of the Society of Materials Engineering for Resources (2008)

Takayoshi SHINDO Shintaro Kodama Sentaro Ozawa

Post-synthetic procedure has been proposed using organo-titanium compounds as Ti source in toluene or aqueous solution to prepare Ti-MCM-41. Ti-MCM-Tn, prepared using Ti-source dissolved in toluene solution, exhibited well-defined 2d-hexagonal structure, and octahedrally coordinated Ti (VI) was mainly introduced as extra-framework species. Ti-MCM-Wn, prepared from Ti-source in aqueous solution, gave high surface area and partially deteriorated 2d-hexagonal structure. Tetrahedrally coordinated Ti (IV) species was selectively incorporated into the framework of the Ti-MCM-Wn samples. Catalytic activity for oxidation reactions of cyclohexene and selectivity to the formation of cyclohexene oxide were correlated with the concentration of Ti (IV) species and the fraction of Ti (IV) in titanium species located at the surfaces of the pores in the Ti-MCM catalysts, respectively.

Competition between vinylidene rearrangement and 1,2-insertion of carbon-disubstituted internal alkynes at a Cp*Ir(iii) complex

Dalton Transactions (2015)

Yousuke Ikeda Shintaro Kodama Noriko Tsuchida Youichi Ishii

Competition between vinylidene rearrangement/1,1-insertion and 1,2-alkyne insertion into the Ir–Ar bond of [Cp*Ir(ppy-F₄)]⁺ was observed on reaction with diarylacetylenes. The former process afforded the 9-membered iridacycle via the subsequent 1,4-Ir migration.
