摘要：

Metal-metal bonding of known bimetallic photosensitizers featuring Ru-Ru, Mo-Mo, Ag-Ag and Rh-Rh bonds was explored using computational modeling benchmarked by established experimental parameters. The analysis reveals that these metal-metal bonds facilitate (1) a red-shift in the maximum absorption wavelength (lambda max) and (2) an increase in the oscillator strength of the lambda max peak. A statistical analysis also reveals a strong correlation between the metal-metal bond order and the oscillator strength. These trends show that metal-metal bonds play a significant role in enhancing the photophysical properties of photosensitizers and inform future photosensitizer designs. Metal-metal bonds facilitate a red-shift in the maximum absorption wavelength and an enhancement of the oscillator strength in photosensitizers.
