Herein we report the self-amplified depolymerization of an aryl oligo(thiourethane) (OTU) for the release of COS/H<sub>2</sub>S. The OTU was synthesized via polyaddition of 4-isothiocyanatobenzyl alcohol and end-capped with an aryl azide. The aryl azide chain-end was reduced by tris(2-carboxyethyl)phosphine or H<sub>2</sub>S to the corresponding aniline, resulting in depolymerization (i.e., self-immolation) and the release of COS/H<sub>2</sub>S. Depolymerization was monitored by <sup>1</sup>H NM ...[more]
