The rule appears to hold for each instance in which the mechanism of chiral selectivity is known in detail and with many different types of chromatographic system.
WebOct 8, 2024 · Besides, the inner bulk layer preserves the same ACC-containing chiral structure with M3h, but with slightly larger pitch distance of 232 nm (Figure 3c,d). This indicates that additional growth of minerals occurred inside the template, which can be verified by the redshift of the reflection wavelength in following photonic analysis. WebMar 27, 2024 · Chiral films of porphyrin on its own were used for comparison. The sensor based on functionalized nanostructures presented a remarkable stereoselectivity in the recognition of limonene enantiomers, whose ability to intercalate in the porphyrin layers makes this terpene an optimal chiral probe.
