520 ▼a This dissertation describes advances toward creating programmable building blocks and assembling them into new, tailored materials. I describe extended materials formed of bonded sets of cobalt selenide clusters. Rationally designed chemical tra
520 ▼a The cobalt selenide clusters fundamental to this study are members of a larger class of clusters with the M6E8 core (M = metal, E = chalcogen). Chapter 1 introduces this family of clusters and reviews examples of previously made materials.
520 ▼a Chapter 2 unveils a family of site-differentiated clusters, Co6 Se8(CO)x(PEt3)6-x, their substitution reactions, and assembly into bridged dimers and trimers. Electrochemical methods were used to investigate electronic coupling between the cores
520 ▼a Chapter 3 introduces electrocrystallization as a method to synthesize extended, crystalline, solid state compounds from superatomic building blocks. By electrocrystallizing redox-active [Co6Se8] clusters with labile ligands in the presence of an
520 ▼a Chapter 4 presents a metal coordination approach to [Co6Se 8] materials via reactive groups on the capping ligands. The redox-activity and multinuclearity of the superatom components creates a new level of complexity and synthetic sophistication
520 ▼a Finally, Chapter 5 outlines a novel chemical transformation that dimerizes [Co6Se8] units to form a material with an expanded core, [Co12Se16], that exhibits electronic and optical properties distinct from the parent monomer. To accomplish this
520 ▼a These chapters present novel synthetic approaches toward creating [Co 6Se8] materials with tuned dimensionality, size, and extensive charge delocalization.
