Figure 3. Mechanism of enantioselective assembly of NPs.

Figure 3

A, FTIR spectra of original CdTe NPs, purified nanoribbons, and supernatant obtained after 50 h of illumination time. B, Schematic illustration of CdTe phase transition to CdS. C, and E, Models of chiral NPs (C) and chiral NP clusters (E) used in calculations of chiroptical properties. D, and F, Simulated spectra and g-factors for (D) L/R-NPs and (F) L/R-clusters of NPs. Nomenclature for NPs and their clusters is based on the positive (L) and negative (R) optical activity. G, and H, HAADF STEM images of TGA-stabilized truncated tetrahedral CdTe NPs. Scale bars are 15 nm (G) and 5 nm (H). I, High resolution TEM image of TGA-stabilized truncated tetrahedral CdTe NPs.
