1. Objectives
Photochromic dyes are compounds that can reversibly change color upon exposure to light, a property that has garnered considerable interest for various applications including sensors, optical storage, and smart materials. The objective of synthesizing a donor-acceptor Stenhouse adduct (DASA) lies in the exploration and utilization of this unique photochromic behavior. This synthesis aims to create a compound that exhibits distinct optical characteristics when subjected to different wavelengths of light, harnessing the molecular interactions between the donor and acceptor units. The DASA structure allows for a reversible transformation driven by light, meaning that the dye can return to its original state once the activating light source is removed. This property is particularly valuable in the development of smart materials that can adapt to changing environmental conditions. By understanding the synthesis pathway of DASA, researchers can gain insight into how struct
