Microscopic solvation environments in a prototype room-temperature ionic liquid as elucidated by resonance Raman spectroscopy of iodine and bromine

Autobiography of Hiro-o Hamaguchi: Out of the Ordinary

“…60 Microscopic solvation environments in C 4 mim[Tf 2 N] were studied with the use of halides, X 2 and X n − (X = I, Br; n = 3, 5), as molecular probes. 61 Free X 2 and X n − were concomitantly detected indicating that there were two distinct solvation environments in bmimTf 2 N, non-polar environments that solvated free X 2 and polar environments that stabilized X n − . These several pieces of Raman spectroscopic evidence convinced us of our hypothesis.…”

“…Analysis of vibrational cooling kinetics of S 1 trans -stilbene in C 5 mim­[Tf 2 N] (Tf 2 N; 1-butyl-3-methyl-imidazolium-bis­(trifluoromethanesulfonyl)­imide) indicated that the heat dissipation behavior was consistently simulated with diameter L of the domain of the formed local structure, 10 nm < L < 100 nm . Microscopic solvation environments in C 4 mim­[Tf 2 N] were studied with the use of halides, X 2 and X n – (X = I, Br; n = 3, 5), as molecular probes . Free X 2 and X n – were concomitantly detected indicating that there were two distinct solvation environments in bmimTf 2 N, non-polar environments that solvated free X 2 and polar environments that stabilized X n – .…”
