(a) Chemical structure of Py-met-chol (3β-hydroxy-pregn-5-ene-21-(1-methylpyrenyl)-20-methylidene). (b) Emission (right) (λEm = 330 nm, bandwidth 2 nm) and excitation (left) (λEx = 388 nm, bandwidth 2 nm) fluorescence spectra in a bilayer: I1, I3, and IE were measured at 376, 388, and 475 nm, respectively.
