Photodynamic therapy (PDT) of cancers is usually inefficient due to the relatively low level of oxygen in cancer cells; therefore, it needs to combine with other treatment strategies such as chemotherapy or photothermal therapy (PTT) to achieve the best anticancer efficacy. Although porphyrin-containing materials have been widely studied for PDT, the photothermal effect is rarely reported. Herein, nanoscale porphyrin-containing covalent organic polymers (PCOPs) were produced via a room temperature solution based aging method. The resulting nanoparticles possess high photothermal conversion efficiency (21.7%) and excellent photodynamic effect. For the first time, the in vitro and in vivo tests indicated an enhanced antitumor efficacy for PCOP with combined PDT and PTT. This study provides an efficient approach to fabricate nanoCOP and also demonstrates the great potential of porphyrin-containing COP for biomedical applications.
