pH or hydrophobicity? Although many organic photodynamic therapy drugs have proven successful in clinical trials, their hydrophobicity makes assessment of their biological photophysics very difficult. With steady-state and ultrafast spectroscopy, the authors show that for axial ligated silicon phthalocyanines in aqueous media, both the polarity and the pH have drastic effects on their photophysics and functionality as 1O2 sensitizers.
