V-shaped nematogens with the "magic bent angle"

Article abstract of DOI:10.1039/c1cc10577a

V-shaped nematogens 1a-c and 2a-b with benzodithiophene bending units have been synthesised. The derivatives 1a-c comprise a flat core with a bending angle of 109°, which is almost the tetrahedral angle proposed to be optimal in the realization of mesogen
