报告摘要：
      Switchable phototheranostic nanomaterials are of particular interest for specific biosensing, high-quality imaging, and targeted therapy in the field of precision nanomedicine.1 Here, we develop a “one-for-all” nanomaterial (NanoPcTBs) that self-assembles from flexible and versatile phthalocyanine building blocks.2 Fluorescence and reactive oxygen species (ROS) generation could be triggered depending on a targeted, protein-induced, partial disassembly mechanism, which creates opportunities for low-background fluorescence imaging and activatable photodynamic therapy (PDT). We also reported a facile strategy to directly assemble a phthalocyanine photosensitizer (PcS) with an anticancer drug mitoxantrone (MA) to form uniform nanostructures (PcS-MA), which have the capability of undergoing nucleic acid-responsive disassembly.3 On the other hand, the in vivo specific binding between albumin and PcS, arising from the disassembly of injected NanoPcS, was recently confirmed using an inducible transgenic mouse system.4 In addition, we demonstrated that a new, nanostructured phthalocyanine assembly, NanoPcA, inherently possesses the ability to promote highly efficient ROS generation via the type I mechanism.5 Recently, we also demonstrated the first comprehensive molecular design of heavy-atom-free triplet PSs based on thiocarbonyl naphthalimides with excellent potential in PDT.6 Finally, recent progress from our group on the fluorescent probes based on N-heterocyclic carbene (NHC) boranes for HOCl7 will be also presented.
