4-hexanoxyl-4′-undecylene-[10]-acyloxyazobenzene was synthesized using the main materials:phenol
underlenic acid
1-bromo-n-hexane
p-nitrophenol
thionyl chloride
by the substitution
reduction
couping and diazotization methods.A new polymer was prepared by hydrosilation reaction of poly (methylhy-drosiloxane) with the monomer.The chemical structure of the monomer and the polymer was confirmed by 1H-NMR and IR measurements and the full hydrosilation reaction of the polymer was confirmed.The liquid crystalline properties of the monomer and the polymer were investigated by using different scanning calorimetry (DSC) and polarized optical microscopy(POM)
