    • note
    • 2 ≥ 0.998 for all data sets. Clear double exponentiality in the resonance decays of 1 were observed only when they were convoluted with nearby solvent resonances (e.g., alkyl chain and cholesterol cyclic methylene groups). These second components were identified unambiguously to solvent relaxation. The successful fitting to single exponential decays was surprising, particularly for the methyl groups, which are usually nonexponential as a consequence of both free methyl and overall molecular rotations.

    • The photophysical and spectroscopic signatures of the transstilbene substructure in 1 indicate no aggregation of 1 in cyclohexane.

    • note
    • Facile detection of a fast component (gel solid) in the presence of a slow component (gel liquid solution) is expected.
