    • For the small signals and the tiny sizes, the experimental error is quite large (±2 nm). The diameters of the micelles are 2.6 nm for w = 2 (methanol), 2.4 nm for w = 4 (methanol), 3.0 nm for w = 8 (methanol), 2.6 nm for w = 2 (acetonitrile), and 3.8 nm for w = 4 (acetonitrile).

    • note
    • Riter et al. reported that methanol and acetonitrile dissolve in nonpolar solvents in ref 38. We are studying the dynamics in polar solvent/ nonpolar solvent mixtures. The parallel and perpendicular detected fluorescence decays of C343 in near saturated methanol and acetonitrile/heptane mixtures are almost the same within experimental error. Interestingly, the dynamic fluorescence Stokes shifts in the methanol/heptane mixture are observed (∼300 ps, no nanosecond component). However, no dynamic fluorescence Stokes shifts in the acetonitrile/heptane mixture are observed within experimental error. We thus conclude that the slow solvation dynamics in reverse micelles are not arising from the binary solution effect except for the hundreds of picosecond component in methanol/AOT/heptane micelles.
