Fig. 2

a Conceptual illustration of the crosslinking reaction of epoxy supramolecular thermosets (detailed experimental conditions in the Supplementary Methods). Generalized synchronous (b, d) and asynchronous (c, e) 2D correlation spectra of EN-VanEHBP7 calculated from the temperature-dependent FT-IR spectra from 30 – 120 °C (interval: 3 °C) in the regions of 1660−1750 cm-1 vs. 1660–1750 cm-1 (b and c), and 840–950 cm−1 vs. 840–950 cm−1 (d and e), red colors represent positive intensities, while blue colors represent negative intensities. Source data are provided in the Source Data file.
