Extended Data Fig. 2

1H NMR spectra (25°C, CDCl3) of PTBL sample (Mn of 162.6 kg/mol) before (a) and after (b) TBD-triggered degradation. The quantitative conversion of PTBL into TBL, a valuable small molecule that can be employed as a versatile building block for synthesizing sulfur-contained functional materials, thus established PTBL as an external stimuli-triggered degradable polymer with a sensible end of life option.
