A liquid-crystalline poly(iminomethylene) with cholesterol-containing pendant groups

Walree, C. A. van,Pol, J. F. van der,Zwikker, J. W.

, p. 561 - 565 (2007/10/02)

Two poly(iminomethylenes) with cholesterol-containing pendant groups were synthesized.Using an aliphatic spacer, a liquid-crystalline polymer was obtained, with equal amounts of right- and left-handed helices.With phenylene as bridging group, only oligomers resulted, probably for steric reasons.Some novel liquid-crystalline esters of cholesterol are also presented.
