研究目的
Investigating the potential of BODIPY dimers to act as photosensitizers in photodynamic therapy through theoretical prediction.
研究成果
The study concludes that BODIPY dimers, especially those with iodine substituents, show promise as photosensitizers in photodynamic therapy due to their efficient singlet-triplet intersystem crossing and ability to generate singlet oxygen. The theoretical predictions suggest that these systems could be effective in PDT applications, warranting further experimental studies.
研究不足
The study is theoretical and does not include experimental validation of the predicted photophysical properties. The computational methods may underestimate certain properties, such as the wavelengths of the singlet excited states.
