Fig. 2: UV-vis and CD spectra as well as TEM images.

a UV-vis absorption spectra of S-PEB in TCE and MCH/TCE (24:1, v/v) at 288 K. Source data are provided as a Source Data file. b CD spectra of S-PEB in TCE and MCH/TCE (24:1, v/v) at 298 K. The inset is the photograph of S-PEB in different states. Source data are provided as a Source Data file. TEM images of the supramolecular polymers of (c) S-PEB and (d) R-PEB prepared from MCH/TCE solution.
