Abstract

Certain molecules (photochromic compounds), when exposed to the light of a specific wavelength, undergo a reversible "isomeric" transformation which leads to reversible changes in some physicochemical properties. Azobenzene derivatives are an example of a photochromic compound that undergoes "cis-trans isomerization" upon irradiation with UV-visible light. Azobenzene derivatives have been previously found to form dynamic photo-responsive supramolecular aggregates. This research aims to further investigate the properties of azobenzene derivatives, and an in-depth understanding of how they form, if at all, dynamic photo-switching aggregates. To evaluate, and study the properties of these molecules, experiments such as solubility, irradiation, and pH experiments were conducted.
