Thermotropic polyketones: a new class of main-chain liquid crystalline polymers

TL;DR: The first examples of thermotropic liquid crystalline (LC) polyketones have been synthesized by the Friedel-Crafts acylation of biphenyl, fluorene and terphenyl with α,ω-dicarboxylic acid alkanes in a phosphorous pentoxide/methanesulfonic acid (PMMA) condensing agent as mentioned in this paper.
Journal ArticleDOI

Polymer Effect on Heterochiral Molecular Recognition in Molecular and Macromolecular Pairs of Liquid Crystals of (R)- and (S)-2-Chloro-4-Methylpentyl 4'-((8-(Vinyloxy)Octyl)Oxy)Biphenyl-4-Caroxylate Enantiomers

TL;DR: In this paper, the phase behaviors of (R)-8 and poly(S)-8 enantiomeric pairs were characterized and compared with those of (S)-6 and (S-8) enantiomers.
Journal ArticleDOI

Intramolecular charge transfer complexes: 2. Poly(2-naphtyl methacrylate-co-picryl methacrylate)

TL;DR: In this paper, a charge transfer complex (CTC) having a 1∶1 composition was obtained in chloroform solutions, and the obtained copolymers are intramolecular CTC, and their charge transfer interactions depend on copolymer composition and conformation.
Journal ArticleDOI

Molecular engineering of liquid crystalline polymers by living polymerization. XVII. Characterization of poly{10‐[4‐cyano‐4′‐biphenyl)oxy]decanyl vinyl ether}s by 1‐D and 2‐D 1H‐NMR spectroscopy

TL;DR: In this paper, the influence of molecular weight on the phase transitions of poly(omega-((4-cyano-4'-biphenyl)oxy)alkyl vinyl ethers with alkyl groups from ethyl to undecanyl was elucidated.
Journal ArticleDOI

Conformationally Flexible Dendronized Cyclotetraveratrylene (CTTV) Self-Organize a Large Diversity of Chiral Columnar, Frank-Kasper and Quasicrystal Phases

TL;DR: In this paper , the conformationally flexible monodisperse tetramer of veratrole, known as cyclotetraveratrylene (CTTV), was used as an apex model to compare with the less flexible corresponding trimer known as CTV and with the rigid triphenylene (Tp) and 1,3,5-trihydroxybenzene (THB) when dendronized with libraries of self-assembling dendrons and with n-alkyl groups.
