A Rationally Engineered Ru(II) Complex with Long Triplet Lifetime and High Emission Quantum Yield for Imaging-Guided Type I/II Photodynamic Therapy
Traditional Ru(II)-based photosensitizers (PSs) face a critical dilemma: short triplet metal-to-ligand charge-transfer (3MLCT) lifetimes limit reactive oxygen species (ROS) generation, while long-lived ligand-centered (3LC) states quench 3MLCT emission, hindering desirable imaging-guided PDT. Herein, fused thiophene...
