Creating nanoparticle dimers has attracted extensive interest. However, it still remains a great challenge to synthesize heterodimers with asymmetric compositions and synergistically enhanced functions. In this work, we report the synthesis of high quality composed porphyrinic nanoscale metal-organic frameworks (nMOF) lanthanide-doped upconversion nanoparticles (UCNPs). Due dual optical properties inherited from individual their interactions, absorption low energy photons by UCNPs is followed transfer nMOFs, which then undergo activation porphyrins generate singlet oxygen. Furthermore, strategy enables tunable UCNP size NIR light harvesting functionality. We demonstrated that hybrid architectures represent promising platform combine NIR-induced photodynamic therapy chemotherapy for efficient cancer treatment. believe such are capable expanding potential applications in solar cells, photocatalysis, nanomedicine.
