Understanding Photophysics of Metallated Tetrakis(CumylPhenoxy) Phthalocyanines in Epoxy and PMMA

The effects of incorporation into a solid matrix on the photophysical properties of a nonlinear material have been of interest for some time in our group. It is well known in the literature that for a nonlinear absorbing dye to be the most effective, high concentrations are generally needed. Understanding how the larger concentration and placement into a solid matrix affects their photophysical properties is the key of this study. Here we look at two metallated substituted tetrakis(cumylphenoxy) phthalocyanines with either Pb or In as the central metal. A detailed study of their photophysical properties based on concentration allows for a better understanding of the constraints this environment has to a given material.
