A rational strategy for the realization of chain-growth supramolecular polymerization
TLDR
The realization of chain-growth polymerization is reported by designing metastable monomers with a shape-promoted intramolecular hydrogen-bonding network that enables optical resolution of a racemic monomer.
An autonomous actuator driven by fluctuations in ambient humidity.
TLDR
An unprecedented film actuator that seemingly operates autonomously is reported, because it responds to the adsorption and desorption of a minute amount of water, possibly induced by fluctuations in the ambient humidity.
Cyclic block copolymers for controlling feature sizes in block copolymer lithography.
TLDR
This study demonstrates that macromolecular architecture is also a powerful tool for tuning domain spacing, and a new synthetic strategy for cyclic block polymers based on highly efficient "click" coupling of difunctional linear chains is developed.
Revisiting thiol‐yne chemistry: Selective and efficient monoaddition for block and graft copolymer formation
The untapped potential of radical thiol-yne mono-addition chemistry is exploited to overcome the known limitations of thiol-ene chemistry in polymer coupling and block copolymer formation. By careful
Ferroelectric Columnar Liquid Crystal Featuring Confined Polar Groups Within Core–Shell Architecture
TLDR
A ferroelectric response is reported for a columnar liquid crystal adopting a core–shell architecture that accommodates an array of polar cyano groups confined by a hydrogen-bonded amide network with an optimal strength.
Liquid crystalline corannulene responsive to electric field.
TLDR
An amide-appended corannulene derivative with tribranched paraffinic side chains self-assembles into a hexagonal columnar liquid crystalline (LC) mesophase that responds to an applied electric field and can align homeotropically to the electrode surface.
Thermally bisignate supramolecular polymerization.
TLDR
A supramolecular polymerization that occurs upon heating as well as cooling is reported, which may lead to supramolescular polymers with tailored complex thermoresponsive properties.
Columnar liquid crystal with a spontaneous polarization along the columnar axis.
A fan-shaped molecule (2), carrying hydrogen-bonding amide groups in proximity to its polar aromatic core, self-assembles into a columnar liquid crystalline mesophase, which unprecedentedly possesses
Functionalization of Azapentabenzocorannulenes by Fivefold C-H Borylation and Cross-Coupling Arylation: Application to Columnar Liquid-Crystalline Materials.
TLDR
The present method expands the variety and utility of azapentabenzocorannulenes as promising π-conjugated cores by an iridium-catalyzed fivefold C-H borylation reaction that exhibits excellent regioselectivity.
Electric-field-responsive handle for large-area orientation of discotic liquid-crystalline molecules in millimeter-thick films.
TLDR
It is reported that aromatic amides with branched paraffinic tails, when properly spaced from mesogenic discotic cores, serve as an E-field-responsive handle that enables large-area unidirectional orientation of columnarly assembled LC molecules with extended p-conjugated cores.
