摘要:

We have investigated the mesomorphic behaviour of a partially deuteriated side chain LC polymethacrylate, poly[4-[6-methacryloyloxyhexyl-oxy]-4′-methoxyazobenzene], by means of2H NMR, DSC and optical microscopy. Evidence for a phase transition occurring in the middle of the nematic phase has been found.
