Molecular and supramolecular deformations and disclinations in a liquid crystalline copolyether thin films under an electrostatic field

Fengchao Xie, +8 more
- 01 Mar 2001 - 
TL;DR: An alignment study of a liquid crystalline copolyether TPP-7/11(5/5) thin films has been carried out in a 10 kV. cm(-1) electrostatic field parallel to the thin film surface normal as discussed by the authors.
Journal ArticleDOI

Intramolecular charge transfer complexes. VIII. Poly[N-(2-hydroxyethyl) carbazolyl acrylate-co-2,4-dinitrophenyl methacrylate]

Cristofor I. Simionescu, +2 more
- 01 Mar 1982 - 
TL;DR: In this paper, a simple terminal mechanism has been described for copolymerization of N-(2-hydroxyethyl) carbazolyl acrylate with 2,4-dinitrophenyl methacrylate (DNPM, M2).
Journal ArticleDOI

Functional polymers and sequential copolymers by phase transfer catalysis. VII: Synthesis and characterization of alternating block copolymers of aromatic poly(ether sulfone)s with aliphatic polysulfides and aliphatic polysulfones

Virgil Percec, +2 more
- 01 Sep 1984 - 
TL;DR: In this paper, α,ω-di(phenol)aromatic poly(ether sulfone)s were polyetherified with tetrabutylammonium hydrogen sulfate as phase transfer catalyst, in a two phase system of 50 wt% aqueous NaOH solution and monochlorobenzene.
Journal ArticleDOI

Intramolecular charge transfer complexes: 19. Copolymers having as acceptor structural units 3,5-dinitrobenzoic acid derivatives with different distances from the main chain

Virgil Percec, +2 more
- 01 Jul 1981 - 
TL;DR: In this paper, the acceptor group and the double bond for a series of monomers baaed on 3,5-dinitrobenzoic acid, the homopolymerization tendency is decreased, allowing evidence of complex participation in copolymerization with the donor monomer N-(2-hydroxyethyl)carbazolyl methacrylate.
Journal ArticleDOI

Heterochiral Molecular Recognition in Molecular and Macromolecular Pairs of Liquid Crystals of 4′-(11-Vinyloxyundecanyloxy)Biphenylyl (2R,3S)- and (2S,3S)-2-Fluoro-3-methylpentanoate Diastereomers

Virgil Percec, +1 more
- 01 Aug 1995 - 
TL;DR: In this article, the phase behavior of diastereomers with well-defined molecular weight and narrow molecular weight distribution was characterized and their corresponding homopolymers with well defined molecular weight were synthesized and characterized.
