Study of the Light Sensitivity of Podophyllotoxin and Its Derivatives
Podophyllotoxin and its derivatives are very light （UV） sensitive, and can be readily photo-ionized to produce some transient species. The laser flash photolysis of podophyllotoxin and its derivatives has been performed for the first time. The mechanism of photo-ionization has been confirmed and illustrated. In addition, the pKa and the molar extinction coffients of the transientn species have been determined.
