Precise molecular engineering is the most fundamental and even a great challenging task for development of small organic fluorophores used as phototheranostic agents in multimodal imaging-guided synergistic therapy. To best our knowledge, there have been no previous reports regarding fine fabrication structure from proof-of-concept study, providing single molecule with all modalities. Herein, an electron donating–accepting (D–A) system constructed by using triphenylamine derivatives donors diverse electron-deficient partners acceptors, yielding aggregation-induced emission luminogens tunable wavelength (up to 933 nm) light absorption capability (ε up 6.9 × 104 M–1 cm–1). Notably, integrating spin–orbit coupling-promoted carbonyl group strong stretching vibrations −CN D–A systems, highly performing agent, namely, MeTIC, constructed. When encapsulating MeTIC into nanovehicles, obtained nanoparticles show excellent performance multimodality theranostics cancer treatment.

This review presents a robust strategy to design photosensitizers (PSs) for various species. Photodynamic therapy (PDT) is photochemical-based treatment approach that involves the use of light combined with light-activated chemical, referred as PS. Attractively, PDT one alternatives conventional cancer due its noninvasive nature, high cure rates, and low side effects. PSs play an important factor in photoinduced reactive oxygen species (ROS) generation. Although concept photosensitizer-based photodynamic has been widely adopted clinical trials bioimaging, until now, our surprise, there no relevant article on rational designs organic PDT. Furthermore, most published articles focused nanomaterials nanotechnology based traditional PSs. Therefore, this aimed at reporting recent strategies develop innovative enhanced therapy, each example described detail instead providing only general overview, typically done previous reviews PDT, provide intuitive, vivid, specific insights readers.

Abstract The development of highly efficient, multifunctional, and biocompatible sonosensitizer is still a priority for current sonodynamic therapy (SDT). Herein, defect‐rich Ti‐based metal–organic framework (MOF) (D‐MOF(Ti)) with greatly improved sonosensitizing effect simply constructed used enhanced SDT. Compared the commonly TiO 2 , D‐MOF(Ti) results in superior reactive oxygen species (ROS) yield under ultrasound (US) irradiation due to its narrow bandgap, which principally improves US‐triggered electron–hole separation. Meanwhile, existence Ti 3+ ions, also exhibits high level Fenton‐like activity enable chemodynamic therapy. Particularly, US as excitation source SDT can simultaneously enhance reaction achieve remarkably synergistic outcomes oncotherapy. More importantly, be degraded metabolized out body after completion therapeutic functions without off‐target toxicity.
