Fig. 2: Bulk Identification of Chirality of Monomers, Repeating Units and Polymers with Same Connectivity but Different Chirality.
From: Unravelling emergence of chirality in click-chemistry polymers down to the single-chain level
Scheme of the SuFEx reaction pathways illustrating the synthesis of a racemic (rac-) and chiral (χ-) monomers with link-monomers to form: b rac- or χ-polymers; and the (c) repeating units, representing the building block of the polymer. d–f CD spectra of monomers, rep. units and polymers. g–i Left: IR Spectra and loading plots of PC1 in the range from 1760–1200 cm−1. For rac- and χ- monomers and repeating units: N = 8 independent experiments, n = 40 spectra each with 512 co-averaging; rac- and χ- polymers: N = 9 independent experiments, n = 50 spectra each with 512 co-averaging. g–i Right: PCA score plots analysis of rac- and χ- monomers, repeating units, polymers indicate statistically significant differences in the C = O and CH regions (see Fig. 3).
