Liquid-crystalline composition of matter

Improved liquid crystalline materials may be prepared by doping liquid crystalline materials with chiral, uncharged metal compounds of formula &lsqb;(P &mdash;Y &mdash;A &mdash;Y &mdash;M &mdash;Y &mdash;) L&rsqb; Me or &lsqb;(P &mdash;Y &mdash;A &mdash;Y &mdash;M &mdash;Y &mdash;) L&rsqb;Me(L&prime;(&mdash;Y &mdash;M &mdash;Y &mdash;A &mdash;Y &mdash;P ) ) . Groups P and P may be, independently, hydrogen, C -C -alkyl groups, polymerizable groups, or radicals containing a polymerizable group. Y to Y may be, independently, single chemical bonds, ether groups, thio groups, carbonyl groups, acid groups, etc. Groups A and A are spacers having from 1 to 30 carbon atoms, and M and M are mesogenic groups. Me may be a transition metal from the fourth, fifth or sixth period of the periodic table, except for technetium, silver, cadmium, gold, mercury, or any of the lanthanoids, or Me may be a main group element from group 14 (IUPAC system), except for carbon and lead. L is a tridentate ligand, and L&prime; is an organic group having up to 12 carbon atoms.
