Extended Data Fig. 2: Solubility of the resultant sulfur-rich polymers.

a, Comparison of solubility of the poly(S-DIB) produced under thermal, thermal + Zn(DTC)2, light of 435 nm and 380 nm. The picture taken within a few minutes after solvents (1 mL) were added into the vial contained polymers (5 mg). b, Representatives of solubility in DMF for sulfur-rich polymers presented in this study. c, Comparison of the solubility in DMF for selected samples without (top, A) and with (bottom, B) grinding + sonication at 60 °C for 40 min.
