Hypericin, Hypocrellin, and Model Compounds:  Steady-State and Time-Resolved Fluorescence Anisotropies [PDF]

, 1998
Steady-state and time-resolved fluorescence anisotropies of hypericin, hypocrellin, and five other analogues have been measured. The steady-state excitation anisotropies for each of these compounds has a broad minimum at ∼400 nm with a negative value. At
