Abstract
Four new homologues series of soft condensed materials consisting of biphenyl
unit connected to different core systems, namely phenyl and naphthalene have been
successfully prepared and characterized. The physical measurement and elemental
analysis (CHN microanalysis), FT-IR, 1D and 2D-NMR spectroscopic techniques
were employed to elucidate the molecular structures of the synthesized compounds.
The liquid crystal properties and thermal behavior of all title compounds were
conducted by POM and DSC. The homologues in the first series comprising a phenyl
ring armed by a biphenyl unit with various flexible terminal alkoxy chains, OCnH2n+1
(n = 7-12) at one end and the other end was attached by aromatic imine with terminal
p-methoxy substituent.
