摘要：

Although metal-based chemical agents have demonstrated promising bacteriostatic effects in phototherapy, their short excitation/emission wavelengths and inadequate phototherapy efficiencies make their application in vivo difficult. We therefore synthesized a novel Pt(II) metallacycle (Pt1110) that can be activated with a 980 nm laser for photodiagnosis/treatment in deep tissue. We found that Pt1110 significantly improved photothermal conversion (95% improvement) and O-1(2) generation (phi(& UDelta;) 75% increase) compared to the ligand itself 1 and was well capable of light-induced sterilizati...
