Abstract

Naturally occurring cholesterol and α-chloroalkanoyl units derived from natural α-amino acids (l-valine, l-leucine, and l-isoleucine) have been utilized to prepare three different series of nonsymmetric liquid crystal dimers. Tolane (diphenylacetylene), which is known to possess several promising structural features, has been chosen as the other mesogenic segment to covalently tether with cholesterol through a flexible spacer. In each series, the ...
