Abstract
We have designed novel liquid crystalline compounds in which two mesogenic units are connected via cis‐2‐buten‐1,4‐diol. We prepared cis‐4‐{6‐[4‐(4‐cyanophenyl)phenyloxy]hexyloxy}‐1‐{6‐[4‐(4‐methyloxy)phenyloxy]hexyloxy}‐2‐butene (6OCMBCB), cis‐1,4‐bis{6‐[4‐(4‐cyanophenyl)phenyloxy]hexyloxy}‐2‐butene (6OCCBCB) and cis‐1,4‐bis{6‐[4‐(4‐methyloxy)phenyloxy]hexyloxy}‐2‐butene (6OMMBCB), and investigated their transition properties. 6OCMBCB and 6OCCBCB exhibited nematic phases whereas 6OMMBCB showed no liquid crystalline phase. We discuss the effects of the mesogenic structure and linkage group on the transition behaviour of the dimesogenic compounds.Keywords
