Ethylene bis-heterocycle compounds have attracted great attention as a new type of photochromic material in recent years. Studies have shown that these compounds have very good thermal stability, fatigue resistance and the advantages of rapid response, and so have highly potential as a new type of functional materials in optical information storage, optoelectronic switches, information display, camouflage materials, and security printing applications. At present, the design and synthesis of new photochromic with good properties of diarylethene compounds is still hot spots in the field of research. Accordingly, the paper design and synthesis of a new photochromic compound 1,2 - bis [2 - methyl -5 - (3,4 - difluorophenyl) thiophene -3 -- yl] cyclopentene perfluoro (DT-1), the photochromic compounds, such as reaction Eq. 1, The synthetic route is as follows |
