Abstract
A cholesteric liquid crystal. The liquid crystal includes a metal acetylide, of which the metal is a square, planar transition metal. The metal acetylide includes first and second acylphosphine ligands and first and second phenyl acetylene ligands. Each of the first and second phenyl acetylene ligands have a meta- or para-substituent, which are selected from the group consisting of H, F, CN, OCH3, C≡C—C6H5,(COO—C34H50O2), and COO—C5H10—C))—C34H50O2.
