Microenvironments, Binding Interactions, and Photophysics of Polyelectrolyte-Bound Tris-(2,2'-Bipyridine)ruthenium(ii)

This research concerns the understanding of the underlying factors and mechanisms which give rise to the altered photophysical behavior and nonexponential decay kinetics of tris-(2,2$\sp\prime$-bipyridine)ruthenium(II) (Ru(bpy)$\sb3\sp{2+}$) upon immobilization in "organized" or inhomogeneous media. To gain a fundamental understanding of these factors and mechanisms it was necessary to characterize the interactions between the complex and the medium of interest, which in this study was poly(styrenesulfonate) (PSS). This thesis addressed three basic questions: (1) How does the complex interact with the polyelectrolyte? (2) How do these interactions affect the photophysics of the complex? (3) How can the decay kinetics be described in chemical terms?
