Development and Investigation of the Fluorescence of Cyclopropenium Ions

The work presented herein employs cyclopropenium ions as a central design element towards the goal of developing fluorescent, superbasic and boronium-substituted compounds. A novel guanidine-cyclopropenimine proton sponge with exceptional basicity is reported that was further utilized to develop a stable tetracoordinate boronium-substituted proton sponge. A large focus of this thesis was also placed on the development of the recently discovered fluorescence of cyclopropenium ions leading to a new class of small molecule organic fluorophores. Among this new platform of fluorescent compounds, a specific fluorophore featured an impressive photophysical profile that bodes well for future applications in fluorescent imaging techniques. Insight into the structure, electronics, bonding and photophysical properties of these derivatives is offered.
