Abstract: Dendritic molecules have demonstrated the ability to encapsulate metal cluster cores and shield them from an external environment. The ability to shield the metal cluster core results in altering of some of the measurable properties of that metal cluster. We propose to obtain photophysical and electrochemical data on an octahedral metal cluster dendrimer. This rhenium-selenide metal cluster was chosen as the dendrimer core because previously characterized rhenium-selenide metal clusters have been demonstrated to luminescence and possess accessible electrochemistry. For these investigations a dendron that has previously exhibited encapsulation and still allowed access to an electroactive will be used. These dendrons will be slightly modified in order to attach them to the rhenium-selenide core. Photophysical and electrochemical investigations will be done on these dendrimers, generations zero through two.
