The synthesis and characterization of side-chain liquid crystalline (LC) polyacrylates containing para-nitroazohenzene (Pn) as mesogenic groups were described. Homopolymers with 3 and 4 carbon atoms in the spacers were non-LC polymers; for homopolymers with 6 carbon atoms in the spacer, nematic LC b
Several novel mesogenic spiro-orthoester monomers such as 1,6,10trioxaspiro [4,5]decanes 4, containing biphenyl mesogens at the C-8 positions of the fiveand six-membered spirocyclic ring, through the alkylene spacers of different lengths were prepared by condensation reaction of the corresponding bi
