A new family of mol. photoswitches based on arylidenehydantoins is described together with their synthesis and photochem. and photophys. studies. A series of hydantoin derivatives have been prepared as single isomers using simple and versatile chem. in good yields. Our studies show that the photostationary states of these compounds can be easily controlled by means of external factors, such as the light source or filters. Moreover, the detailed investigations proved that these switches are efficient (i.e., they make efficient use of the light energy, are high fatigue resistant, and are very photostable). In some cases, the switches can be completely turned on/off, a desirable feature for specific applications. A series of theor. calculations have also been carried out to understand the photoisomerization mechanism at the mol. level. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1Safety of 3,5-Dibromo-4-methoxybenzaldehyde).
3,5-Dibromo-4-methoxybenzaldehyde (cas: 108940-96-1) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
