Cascade‐Microphase‐Separation‐Induced Hierarchical Photonic Structures in Supramolecular Organogel for Deformation‐Insensitive Structural Colors

Advanced Optical Materials, 2019
Photonic materials with tunable structural colors in response to various stimuli have enabled diverse sensing and displaying applications. However, the changeable colors caused by mechanical deformations may severely confuse the optical readouts for the ...

Organogelation of Sheet–Helix Diblock Copolypeptides

Angewandte Chemie, 2008
Together they're strong: Block copolypeptides containing poly(benzyl-l-threonine) and an α-helical block are effective organogelators despite the high solubility of the constituent homopolymers. An unexpected conformational change in the first block, from random coil to β sheet, directs the assembly into stacked lamellae (see picture).

A New ex-TTF-Based Organogelator: Formation of Organogels and Tuning with Fullerene

Langmuir, 2010
A new ex-TTF-based organogelator with L-glutamide-derived lipid unit (compound 1) was synthesized and characterized. The resulting transparent organogels can be obtained with several organic solvents such as toluene, DMSO, and ethanol. It is interesting that its gelation ability can be further enhanced by addition of C(60).

Macroscopic Layered Organogel–Hydrogel Hybrids with Controllable Wetting and Swelling Performance

Advanced Functional Materials, 2018
Soft gels that integrate the water retention of hydrogels and the water swelling resistance of organogels are sought by researchers. Such materials have useful properties and potential applications in stretchable and biointegrated fields, such as tissue ...

Dispersion of single walled carbon nanotubes in organogels by incorporation into organogel fibers

Journal of Colloid and Interface Science, 2010
We prepared hybrid organogels, where single walled carbon nanotubes (SWNTs) were incorporated into organogel fibers. The SWNTs were covalently functionalized with organic branches that had a similar structure to the organogelator. The effect of relative interactions between the carbon nanotubes (CNTs), organogelator, and solvent molecules on the hybrid

Electrocatalytic Oxygen Evolution in Acidic and Alkaline Media by a Multistimuli-Responsive Cobalt(II) Organogel

ACS Sustainable Chemistry and Engineering, 2019
Supramolecular gels and metallogels involving dynamic and reversible noncovalent interactions are touted as alternatives to gels based on polymeric materials for practical purposes and for an obvious edge in tailorability.

Polymer organogelators that make supramolecular organogels through physical cross-linking and self-assembly

Chem. Soc. Rev., 2010
This tutorial review highlights recent and current advances in polymer organogelators, which are rare compared with low molecular weight gelators. In this review, we classify polymer organogelators in three categories: the formation of supramolecular crosslinking points by conformational changes, the addition of crosslinking agents and the self ...

Reaction-based chiroptical sensing of ClO- using circularly polarized luminescence via self-assembly organogel.

Chemical Communications, 2019
By covalent combination of a chiral amino acid, lipid, and achiral phenothiazine derivative, a reaction-based chiroptical probe, PTZ-D, was obtained. PTZ-D could self-assemble into a chiral organogel realizing the chirality transformation from a chiral ...

Small‐Peptide‐Based Organogel Kit: Towards the Development of Multicomponent Self‐Sorting Organogels

Chemistry – A European Journal, 2013
AbstractThe results presented here highlight the extremely useful nature of ultra‐short peptides as building blocks in the development of smart multicomponent supramolecular devices. A facile bottom‐up strategy for the synthesis of a small library of stimuli‐responsive smart organogelators has been proposed based on the predictive self‐assembly of ...
