Abstract
Herein, we report a microporous carbon nanomaterial that was generated from a nanoscale covalent organic framework precursor via a simple pyrolysis approach. The obtained carbon-based nanoparticles possessed a broad NIR absorption capacity and exhibited a high level of photothermal conversion ability (η = 50.6%) in the NIR-II biowindow. Its excellent PTT antitumor efficiency was fully evidenced by in vitro and in vivo experiments under 1064 nm laser irradiation.
