Understanding the Role of Energy in Chemical Reactions from Mechanics to Photochemistry

McKissic, Kelley S

Abstract Details

2015, PhD, University of Cincinnati, Arts and Sciences: Chemistry.
In order for a chemical transformation to occur, enough energy must be placed in the system to overcome the activation barrier, making energy the key component of all chemical reactions. Although thermal energy is more traditionally used in this capacity, photochemical and now mechanochemical energy has played a prominent role in promoting chemical reactions to occur. This work will focus on extending the fundamental chemistry of corannulene in both photochemical as well as mechanical environments, where studies on nitrogen based corannulene derivatives such as, nitrocorannulene, azidocorannulene, and azoxycorannulene dimer were performed. Where the photochemistry of 1-nitro corannulene better resembles 2-nitropyrene not 1-nitropyrene; and the photochemistry of 1-azidocorannulene better resembles vinyl azides rather than phenyl azides. In the case of the azoxycorannulene dimer, this represents first corannulene-based molecule synthesized in a mechanochemical ball milling environment and studied photochemically. To further the study of energy of a Spex 8000M mixer/mill we determined a way to measure the relative amount of energy generated in this environment using Diels-Alder reactions and found the conditions were equivalent to roughly 90 °C thermally.
