A Survey on the Synthesis of PhotochromicMaterial Diarylethe-nes

Due to the potential applications to many fields, photochromic compounds as functional materi- als have been widely focused. In particular, diarylethenes have become the promising candidates of photo- chromic compounds because of the excellent thermal stability of both isomers and resistance to high fatigue. Numerous studies on the synthesis and characters of photochromic diarylethene derivatives have been car- ried out in various research fields, such as memory media, optical switching, logic circuit, liquid crystal dis- play and magnetic materials. In this paper, the methods of preparations of photochromic diarylethenes are reviewed. Based on current research and existing products, some new and future approaches in this fascinat- ing area are thoroughly discussed.
