(Macromolecules) Polysiloxane-Based Liquid Crystalline Polymers and Elastomers Prepared by Thiol-Ene Chemistry
A series
of side-chain liquid crystalline polymers (LCPs) with polysiloxane backbones
have been synthesized by grafting mesogenic monomers to
poly[3-mercaptopropylmethylsiloxane] (PMMS) via thiol-ene click chemistry. Moreover, by controlling the molar ratio of PMMS and
mesogenic monomers, PMMS-based LCPs can be
partially functionalized, meanwhile leaving spare mercapto groups, which can be
fu...

(J. Mater. Chem. C) Mesogen-Jacketed Liquid Crystalline Polymers and Elastomers Bearing Polynorbornene Backbone
This
manuscript describes a series of mesogen-jacketed liquid crystalline polymers
(MJLCPs) and elastomers (MJLCEs) bearing a novel polynorbornene backbone, onto
which the liquid crystalline mesogen is laterally attached by a single covalent
bond without spacers.

(Macromolecules) Amphiphilic Poly(Ethylene Oxide)-block-Poly(Butadiene-graft-Liquid Crystal) Copolymers: Synthesis and Self-Assembly in Water
What could be the self-assembly behaviour in aqueous
solution for an amphiphilic block copolymer with a very flexible hydrophobic
backbone possessing however a liquid crystalline (LC) order? To answer this
question, five amphiphilic block copolymers were prepared by grafting, via a
thiol-ene addition reaction, four different thiol functionnalized LC mesogens
or LC-like side groups on two commerc...

(JACS) Micron-Sized Main-Chain Liquid Crystalline Elastomer Actuators with Ultra-Large Amplitude Contractions
Responsive surfaces composed of cylindrical or square micrometer-sized thermoresponsive pillars made of thiol-ene nematic main-chain liquid crystalline elastomers (LCEs) are produced by replica molding. The individual pillars behave as microactuators, showing ultralarge and reversible contractions of around 300-400% at the nematic to isotropic phase transition. The nematic main-chain LCE microac...

The stability of covalently immobilization of TEMPO on the polymer surface through ionic liquid linkage: a comparative and model research.
Covalently immobilizing the active sites or ligands on a polymer surface is an efficient strategy to achieve a full use of expensive organic parts. In this work, 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) was anchored onto polystyrene beads through an ether bond or an ionic liquid bridge. We quantitatively compared their thermal stabilities at nitrogen atmosphere and their chemical stabilities i...

Temperature-sensitive hydrogel modified by polymerizable liquid crystal AAc-Brij-58: optical and protein adsorption/desorption behaviors
To avoid template-like action of polyoxyethylene 20 cetyl ether (Brij-58) in hydrogel matrix, a polymerizable liquid crystal AAc-Brij-58 based acrylic acid (AAc) and Brij-58, and poly(NIPAm-co-AAc-Brij-58) (ACHX) hydrogels based on N-isopropylacrylamide (NIPAm) and AAc-Brij58 were synthesized by esterification and free-radical polymerization. The chemical structures of resulting ACHX hydroge...

200. Catalytic liquid marbles: Ag nanowire-based miniature reactors for highly efficient degradation of methylene blue.
Ag nanowire-based catalytic liquid marbles are fabricated as miniature reactors, which demonstrate highly efficient, support-free and rate-controllable heterogeneous degradation of methylene blue, with catalytic efficiency close to 100%. Our miniature catalytic liquid marbles are essential for reactions involving highly toxic/hazardous or costly reactants, where small volume preliminary reactions ...

199. Plasmonic Liquid Marbles: A Miniature Substrate-less SERS Platform for Quantitative and Multiplex Ultratrace Molecular Detection.
Inspired by aphids, liquid marbles have been studied extensively and have found application as isolated microreactors, as micropumps, and in sensing. However, current liquid-marble-based sensing methodologies are limited to qualitative colorimetry-based detection. Herein we describe the fabrication of a plasmonic liquid marble as a substrate-less analytical platform which, when coupled with ultras...
