Excerpt: ( E )-Stilbene ( E )-Stilbene , is a diarylethene , i.e., a hydrocarbon consisting of a trans ethene double bond substituted with a phenyl group on both carbon atoms of the double bond. The name stilbene was derived from the Greek word stilbos , which means shining. Isomers Stilbene exists as two possible isomers. The first is trans -1,2-diphenylethylene, called ( E )-stilbene or trans -stilbene. The second is cis-1,2-diphenylethylene, called ( Z )-stilbene )-stilbene or cis -stilbene, and is sterically hindered and less stable because the steric interactions force the aromatic rings out-of-plane and prevent conjugation . ( Z )-Stilbene has a melting point of 5-6 °C, while ( E )-stilbene melts around 125 °C, illustrating the two compounds are quite different in their physical properties.
