Figure 3. Characterization of individual states during a light-controlled healing cycle.

Figure 3

(a) Normalized solid state ultraviolet/visible spectra of X@PON on illumination with a 365 nm LED for 8 min to form the ring-closed isomer X@POFF (83% photoconversion in photostationary state, Supplementary Fig. 11 and Supplementary Note 4). (b) FT-IR spectra of X@PON and X@POFF recorded at 25 °C and after heating to 124 °C for 5 min in vacuum. (c) Mesh sizes of X@PON, XON+P and X@POFF measured by SAXS (scattering curves: Supplementary Figs 5, 12, 13 and 20, overview over mesh sizes: Supplementary Tables 1–5, further explanation: Supplementary Note 3). (d) FT-IR spectra of X@POFF (recorded at 25 °C) and X@PON regenerated on illumination with 460 nm LED for 105 min (recorded at 25 °C and after heating to 124 °C for 5 min in vacuum). (e) Temperature dependence of shear storage modulus G′ and shear loss modulus G″ of X@PON and X@POFF.
