Chemistry Organic Chemistry supramolecular aggregation azobenzene photoswitches photoswitching aggregates UV-Vis spectroscopy circular dichroism spectroscopy azobenzene derivatives In the area of photochemistry, many molecules can undergo photoisomerization. Within these photoswitches is a family of molecules derived from azobenzene, which can form what are called supramolecular aggregates. When these molecules are in the presence of one another, they can form large structures. In addition to this, such molecules may also be able to maintain their ability to photoswitch while in a supramolecular structure.These supramolecular photoswitching aggregates have been used in many different applications including hydrogels and sol-gels, and the effort of cataloging and characterization of these molecules is a novel endeavor. Previous testing has concluded that ADA (Azobenzene-4,4’-dicarboxylic acid) and M0423 (4-Dimethylaminoazobenzene4’-carboxylic acid) show aggregation properties as well as photoswitching properties when paired together. When by themselves they show remarkable self-aggregation, however, they both do not show photoswitching properties. ADA shows photoswitchingproperties while M0423 does not. This data was confirmed through additional tests.The addition of the molecule A1598 (Azobenzene-3,3’-dicarboxylic acid) shows shocking similarities in aggregation to ADA in addition to possessing its own unique attributes. A1598 was confirmed to have formed aggregates with itself and M0423. These tests also confirmed a preferred pH and mixing ratio for the ADA and A1598-M0423 aggregate as well as assessing their photoswitching capabilities and aggregation under the stresses of photoswitching. Showing that both molecules when aggregated, regardless of the high degree of order displayed in the spectra, locked up. This prevented further photoswitching from occurring. This research shows that there is still more that can be learned from these molecules and similar azobenzene derivatives with respect to photoswitching aggregates. 2020 English text University of Dayton / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=dayton1608140810691289 http://rave.ohiolink.edu/etdc/view?acc_num=dayton1608140810691289 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
