  Cholestane-based liquid crystals containing a difluorooxymethylene bridge

  摘要：

  A new class of steroid-based liquid crystals was synthesized and characterized with regard to their mesogenic and chiroptical properties. The beta-selective formation of the cholestanyl difluoromethyl ether bridge was achieved by an oxidative fluorodesulfuration procedure. (C) 2005 Elsevier B.V. All rights reserved.
