Fig. 5. (a) CD and UV-vis spectra of hollow trimeric nanotubes (0.05 mM) prepared by mixing 1 and 2 (black lines), and by removing DBB and MeOH of the pS-rich nanotubes constructed via pre-regulation (green lines). (b) CD change of trimeric nanotubes (0.05 mM) at 311 nm after removing DBB and MeOH. The spectra were recorded at 20 °C in chloroform.
