Abstract:
Data are reported which permit one to explain the photodynamic phenomenon as an energy transfer of importance in biology and medicine as well as of interest in physical chemistry. A study carried out with the help of ESR is considered; the experimental conditions influencing signal production appear to be the same as those determining the effect observed with other methods in the same photodynamic system. A scheme is proposed, where the sensitizer is excited to a triplet state, which combines with oxygen to form an «oxyradical»: the latter reacts then with the substrate. The importance of the interaction between sensitizer and substrate, possibly by London‐Van der Waals forces, is discussed as a condition for the photodynamic reaction. Complex formation between sensitizer and substrate is also taken into consideration.
