a Temperature-dependent changes in the absorption spectrum of a solution of 6FF in dodecane: [6FF] = 12.5 μM, 373 → 298 K, −5.0 K/min. b Time-dependent changes in the spectrum of a solution of 6FF prepared by quenching a hot dodecane solution (373 K, shown in black line) in an ice bath for 30 s: [6FF] = 12.5 μM, measured at 298 K. c Plots of the absorbance at 403 nm (filled circle) and the temperature of the solution (open circle) over time measured at 298 K. d–g AFM images of the self-assembled 6FF observed during its propagation. Scale bar = 200 nm. The AFM specimens were prepared from solution at the times indicated by the arrows in c: at d 50 s, e 100 s, f 600 s, and g 1200 s.
