The fluorescence and excitation spectra of 2-aminopyridine and 6-hydroxyquinoline indicated a high acidity of [HMIM][TfO]. We also observed the proton transfer from trisodium 8-hydroxypyrene-1,3,6-trisulfonate (HPTS) to 1-methylimidazole (MIM) or water added to [HMIM][TfO] as co-solvent. The fluorescence excitation spectra indicated that the existence of the complex between HPTS and MIM. The fluorescence dynamics indicated that the site selective proton transfer occurred in solid [HMIM][TfO]. In a PC phase, such an unique process was not observed, suggesting that the rotational dynamics in PC was similar to that in liquids phase., application/pdf}, pages = {163--171}, title = {イオン性柔粘性結晶中でのプロトン移動反応の評価}, volume = {63}, year = {2022}, yomi = {ワタナベ, レイ and キムラ, ヨシフミ} }
