New Liquid Crystalline Compounds Based on Thiophene

Brettle, Roger,Dunmur, David A.,Marson, Charles M.,Pinol, Milagros,Toriyama, Kazuhisa

, p. 613 - 616 (2007/10/02)

A homologous series of 2-alkyl-5-(4'-cyanophenyl)thiophenes has been prepared and shown to have improved properties for use in liquid crystal displays.The thiophene ring is prepared from a 1-(4'-bromophenyl)-1,4-dioxoalkane, constructed using the Stetter procedure, by the action of Lawessons reagent, and the cyano-group is finally introduced using a copper(I)-mediated exchange reaction.
