摘要:
A new side chain liquid crystalline polymer with biphenyl mesogenic group has been prepared. This polymer forms a bilayer smectic A phase through intermolecular hydrogen bonding according to the result of X-ray diffraction. Its phase transition was studied lining DSC and polarized optical microscopy. Infrared spectroscopic measurements show that cyclic dimeric hydrogen bonds of carboxylic acids are embedded in the bilayer.
