Abstract

Lithium tetrafluoroborate‐acetonitrile complexes were studied in two liquid crystals, trans,trans‐4‐n‐propyl(1,1′‐bicyclohexyl)‐4′‐carbonitrile (ZLI‐1184) and trans‐4‐pentyl‐1‐(4‐cyanophenyl)cyclohexane (S‐1114). The results indicate the formation of tetrahedral lithium‐acetonitrile complexes and the coordination of lithium from LiBF~4~ and LiClO~4~ with the cyano group of ZLI‐1184. No evidence was found to support either lithium ion complexation with S‐1114 or tetrafluoroborate ordering in any of the systems investigated.

The recently developed NMR SPDE espcriment is shown to provide a new and particvlnrly convenient technique fez probing ti-iz conformational dynamics of mesogcns in thermotropic liquid crystals. Measurements have been made in the nemstic and smcctic pha=s of the 4,4'di-rl-alkaxyazoxybenzenes. It is s
