摘要：

Iridium complex loaded polypyrrole nanoparticles (Ir-PPy NPs) have been prepared through the polymerization of pyrrole by Fe3+ in the presence of polyvinyl alcohol (PVA) and iridium complex. The Ir-PPy NPs exhibited a photothermal effect and the generation of singlet oxygen. In the Ir-PPy NPs, PPy could convert light energy to heat with a photothermal conversion efficiency of similar to 35.5% when irradiated by a 730 nm continuous wave (CW) laser, and the iridium complex could generate singlet oxygen when irradiated by a 730 nm CW laser, as confirmed by monitoring the consumption of DPBF at 410 nm.
