摘要：We propose a noncovalent backbone planarization strategy to fabricate a gas/phototheranostic nanocomposite (B-E-NO NPs) in the near-infrared-II (NIR-II, 1000-1700 nm) window by incorporating noncovalent conformational locks. B-E-NO NPs display a giant NIR-II extinction coefficient, realizing multimodal imaging-guided high-efficiency NIR-II photothermal therapy (eta = 45.4%) and thermal-initiated nitric oxide combination therapy. A simple noncovalent backbone planarization strategy was proposed to achieve an NIR-II-absorbing molecule-based nanocomposite for optimized NIR-II excited gas/phototheranostic applications.
