Nano-micro Letters 2024年第2期16卷 1-14页

massive efforts have been concentrated on the advance of eminent near-infrared(NiR) photothermal materials(PTms) in the NiR-Ⅱ window(1000–1700 nm), especially organic PTms because of their intrinsic biological safety compared with inorganic PTms. However, so far, only a few NiR-Ⅱresponsive organic PTms was explored, and their photothermal conversion efficiencies(PCEs) still rem.in relatively low. Herein, donor–acceptor conjugated diradical polymers with open-shell characteristics are explored for synergistically photothermal immunotherapy of metastatic tumors in the NiR-Ⅱ window. By employing side-chain regulation, the conjugated diradical polymer TTB-2 with obvious NiR-Ⅱ absorption was developed, and its nanoparticles realize a record-breaking PCE of 87.7% upon NiR-Ⅱ light illustration. in vitro and in vivo experiments demonstrate that TTB-2 nanoparticles show good tumor photoablation with navigation of photoacoustic imaging in the NiR-Ⅱ window, without any side-effect. moreover, by com.ining with PD-1 antibody,the pulmonary metastasis of breast cancer is high-effectively prevented by the efficient photo-immunity effect. Thus, this study explores superior PTms for cancer metastasis theranostics in the NiR-Ⅱ window, offering a new horizon in developing radical-characteristic NiR-Ⅱ photothermal materials.
