| Abstract |
The photochromism is a phenomenon in which the spectroscopic characteristics of molecules are reversibly changed by light or light rays at a specific wavelength, and color change occurs. Recently, photochromism for glass and ink have been widely used. Among various photochromic materials, diarylethene series which are excellent in fatigue properties were used in this study.
BTT and mono-BTT, which exhibit photochromic properties, were synthesized from 2-methylbenzo[b]thiophene through boronation reaction and Suzuki reaction. Sulfur atom of mono-BTT was oxidized at room temperature, and then Suzuki reaction was carried out to synthesize BTTO2. When such a reaction was carried out at a high temperature, BTTO4 was synthesized. Photophysical properties of those compounds were studied. We will discuss about the change of physical properties including fatigue properties according to the oxidation degree of sulfur group.
