SynopsisAcrylarnide and methacrylamide derivntives of nucleic acid baws were prepared from the corresponding aminoethyl derivatives. Free-radical polymerization of these monomers in water or in organic solvents gave their polymers. From the studies of the polymer complex formation hy UV spectroscopy. it was found that extremely stable polymer complexes were formed between complementary polymers containing nucleic acid bases.

Ferroelectric liquid crystals (FLC’s) having various cores were synthesized and the effect of the different core structures on the spontaneous polarization (Ps) values was investigated. The results indicate that the core structure has a great influence on the Ps value and introduction of a heterocycles such as pyrimidine and thiadiazole ring in the core increases the Ps value. Moreover, several compounds in this series are interesting as chiral dopants for FLC, because the mixtures containing them showed superior properties as FLC mixture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
