  The heliconical nematic twist-bend phase from “classic” bent-core benzylideneanilines with oligomethylene cores

  摘要：

  We report the synthesis and properties of several new heliconical twist-bend nematic (N-TB) bimesogens possessing classic bent-core benzylideneaniline wings combined with oligomethylene spacers of odd parity. While short alkoxy tails combined with a resorcinol diester core in the classic system appear to give SmA phases (not B2 phases), in the present system, methoxy or ethoxy tails exhibit the N-TB phase as evidenced by textural analysis. Several of these compounds also exhibit microscopic helical defect structures in the N-TB phase, which have been reported in other lamellar and pseudo-lamellar liquid crystal phases, but not in the N-TB phase.
