Extended Data Fig. 6 |. C8S3-Br nanotubes self-assembly over long time.
a Dynamic light scattering (DLS) intensity distributions of C8S3-Br nanotubes in solutions (20% MeOH v/v in MeOH:H2O mixture with 0.2 mM dye concentration) at various time intervals after aggregate preparation. The distribution depicts shorter lengths initially at 10 min and then shifts to drastically longer lengths over a course of 5 weeks. We note that the DLS scattering intensities are related to the hydrodynamic diameters of the freely diffusing nanotubes and can be used to estimate the length of the nanotubes, b. normalized absorption spectra corresponding to each time point showing a slow conversion from nanotubes to bundles, c. and d. representative cryo-EM images of the samples frozen 1 day and 5 weeks after aggregate preparation, respectively.
