Abstract Details

2021, Doctor of Philosophy (PhD), Ohio University, Chemistry and Biochemistry (Arts and Sciences).
The Cucurbit[n]uril (CB[n]) family of barrel-shaped macrocycles is known for their very high affinity towards hydrophobic molecules flanked with positively charged substituents. They have been used for a wide range of applications, including drug delivery, molecular switches, catalysis, and polymers, to name a few. Herein, we first present a CB[8]-based chemosensor that can encapsulate an auxiliary probe to perform hydrocarbon recognition. This insightful study revealed the role of usually neglected weak forces like CH-π interactions in the formation of inclusion complexes. The CB[8] macrocycle was also exploited to synthesize a dynamic dimer of platinum terpyridyl chloride, which is then used as a photocatalyst for water splitting. Using CB[8] successfully increased the catalytic efficiency and provided mechanistic insight into this complex process. At last, we assessed the self-assembling behavior of dibenzyl ammoniums with CB[8]. The impact of quadrupole-quadrupole interactions between the benzyl groups and the desolvation of these groups on guest encapsulation and binding affinities were analyzed thoroughly, both experimentally and in silico.
