Bicyclic aziridines show exclusive photochromic behavior. Here, we summarize the results of optical and electrochemical properties, such as photochemical, solvatochromic, electrochromic andkinetic behavior of bicyclic aziridines linked to chalcone moieties. The photochromic process for conversion of closed photoisomers to open photoisomers for compounds 1-10 followed zero-order kinetics. For considering the solvatochromic properties of compounds 1,3,5,7 and 9, photochromic properties of these compounds in different solvents were investigated and the negative solvatochromism were observed. The redox behavior of several derivatives of bicyclic aziridines by cyclic voltammetry was examined for compounds 1,3,5 and 6, and irreversible oxidation was observed.
