Liquid-crystalline supramolecular polymers formed through complementary nucleobase-pair interactions.
We report how the placement of nucleobase units, thymine, or N6-(4-methoxybenzoyl)adenine, onto the ends of a mesogenic core, bis-4-alkoxy-substituted bis(phenylethynyl)benzene, affects the properties of these materials. We show that addition of these bulky polar groups significantly reduces the range of liquid-crystalline behavior of these compounds. However, mixing two complementary nucleobas...
متن کاملNovel Supramolecular Side-Chain Banana-Shaped Liquid Crystalline Polymers Containing Covalent- and Hydrogen-Bonded Bent Cores
Novel supramolecular side-chain banana-shaped liquid crystalline (LC) polymer complexes AmBn-N bearing various (m/n) molar ratios of hydrogenand covalent-bonded bent-core components were acquired by the free radical polymerization, where the hydrogen-bonded (H-bonded) structures were executed via mixing equimolar portions of proton donor (H-donor) polymers AmBn (homopolymers/ copolymers) and py...
متن کاملSide-Chain Supramolecular Polymers Employing Conformer Independent Triple Hydrogen Bonding Arrays
Derivatives of thymine have been extensively used to promote supramolecular materials assembly. Such derivatives can be synthetically challenging to access and may be susceptible to degradation. The current article uses a conformer-independent acceptor-donor-acceptor array (ureidopyrimidine) which forms moderate affinity interactions with diamidopyridine derivatives to effect supramolecular ble...

The synthesis of H-bonded bent-core side-chain liquid crystal polymers carried out by two alternative synthetic routes and their properties are reported.
متن کاملMolecular organization in side chain liquid crystalline polymers
2014 We have synthesized a series of side chain liquid crystalline polymers which differ only by the terminal end group of the mesogenic moieties. X-ray diffraction experiments show the existence of a lower temperature smectic A phase following the nematic phase, while optical microscopy was not able to show smectic A characteristic textures. The diffraction patterns give information about the ...
