Topological Engineering of NIR-II Emissive Conjugated Oligomers With Unexpected Excited-State Manifolds for Efficient Phototheranostics and Cancer Immunotherapy.
Phototheranostic agents operating in the second near-infrared (NIR-II) window hold great potential for precision cancer therapy, yet the rational regulation of excited-state processes to simultaneously optimize fluorescence and phototherapeutic performances remains a fundamental challenge. Herein, we report a topology-...
