In this study, a Cu(ii)-porphyrin-derived nanoscale COF was developed for PDT against H2S-enriched colon tumors, with controllable singlet oxygen release. The in situ generated CuS can also be used synchronously as a photothermal agent for PTT.
Herin, we report a Cu(ii)-porphyrin-derived nanoscale COF, which can be triggered by endogenous H2S via an intracellular sulfidation reaction to generate a metal-free COF-photosensitizer for PDT against H2S-enriched colon tumors with controllable singlet oxygen release; meanwhile in situ generated CuS can be synchronously used as a photothermal agent for PTT.
