Photophysics of a cyanine dye within cyclodextrin cavity

Abstract The modulated photophysical and dynamical behavior of a potent anti-tumor photosensitizer 3,3/-diethyloxadicarbocyanine iodide (DODCI) following host-guest inclusion complex formation with α-, β- and γ-Cyclodextrins (CDs) has been studied using steady-state and time-resolved spectroscopic methods. The cavity size of the CDs (α-CD
