Pi-Extension and Hypervalency of Conjugated Organophosphorus Compounds (Master's thesis, University of Calgary, Calgary, Canada). Retrieved from https://prism.ucalgary.ca. doi:10.11575/PRISM/27359http://hdl.handle.net/11023/3955The work of this thesis focuses on synthesizing and analyzing new electron-accepting materials that could be beneficial for the development of organic n-type materials for application in organic electronics. The first research chapter focuses on the synthesis of pyridine-extended dithienophosphole oxide compounds in attempts to combine the strong emission of the dithienophosphole oxide backbone with the exciting electrochemical properties of methylated viologens. The motivation for this research and the various synthetic approaches attempted will be discussed in detail. Further, reasoning for the unsuccessful nature of this project will be offered. In the second research chapter, intramolecular Lewis acid/base interactions are formed to produce new hypervalent phosphorus compounds with electron-accepting capabilities. Systematic phosphorus functionalization is performed to allow for manipulation and exploitation of the electrochemical and optical properties of the molecule. Finally, the interactions present in the compounds are rationalized using theoretical calculations.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
