Synthesis and thermal behavior of chiral oligomers derived from cholesterol
摘要:
Synthesis and thermal properties of a series of Schiff base oligomers derived from naturally occurring cholesterol are described. In particular, four of them show smectic A and/or chiral nematic phase/s or an unknown mesophase, while the other is non-mesomorphic. Molecular packing in the SmA phase has been determined by the HRXRD experiment. (C) 2008 Elsevier Ltd. All rights reserved.
