Synthesis and Property of a New Symmetry Diarylethene Bearing Benzene

A new diarylethene of 4-bromo-1-phenylethynylphene was synthesized. It is a kind of conjugated organic molecular that simulated the structural features of left-handed material. The compound turns out to be a single-crystal. Its properties, including X-ray single-crystal diffraction analysis and optical property were investigated in detail.
