Abstract
Liquid crystal mixtutre of donor and acceptor molecules, the first consisting of a liquid crystal compound having an unshared electron pair (the donor) and the second generally consisting of an electron receptive compound such as a p-cyano-p'-alkyl- or alkoxy-substituted bipheny liquid crystal compound (the acceptor); together these compounds form a molecular complex with improved physical properties, including particularly a broader mesophasic temperature range, then would be expected from a simple combination of such liquid crystals.
