Dual-Emissive Self-Reporting Photosensitizers Characterized with Kasha/Anti-Kasha Behaviors Engineered via Gradient Donor-Acceptor Strategy

Real-time monitoring of photodynamic therapy (PDT) is essential for precision medicine, yet remains hindered by microenvironmental interference and photobleaching of conventional mono-emissive photosensitizers (PSs). Herein, inspired by the energy level...
