Mirror symmetry breaking and chiral amplification in foldamer-based supramolecular helical aggregates

Spontaneous asymmetric generation of supramolecular chiral fibers was observed in the folding induced self-assembly of a lock-washer shaped foldamer. A secondary nucleation growth mechanism is proposed to explain the observed chiral amplification or deracemization of these supramolecular fibers.

Light-Harvesting Hybrid Hydrogels: Energy-Transfer-Induced Amplified Fluorescence in Noncovalently Assembled Chromophore–Organoclay Composites

The noncovalent self-assembly of chromophores in an organoclay template results in the formation of fluorescent hybrid hydrogels and films. These clay–dye hybrids act as novel supramolecular scaffolds for light-harvesting as the aminoclay (AC) templates the spatial organization of donor and acceptor molecules to promote Förster resonant energy transfer (see picture; CS=coronene salt, PS=perylene salt).

Aryl Trihydroxyborate Salts: Thermally Unstable Species with Unusual Gelation Abilities

A series of aryl trihydroxyborate salts were synthesized and found to form gels in benzene. The compounds were thermally unstable and readily underwent protodeboronation in solution and the solid state. Gelation could be induced without decomposition via sonication. Subsequent characterization studies revealed an unusual dependence of gel properties on alkyl chain length.

Low Molecular Weight Fluorescent Organogel for Fluoride Ion Detection

The design, synthesis, and the photophysical properties of a Low Molecular Weight Gel (LMWG) based on AB₃ and AB₂ type poly(aryl ether) dendrons with an anthracene chromophore attached through an acylhydrazone linkage are described. The gel is utilized for an efficient ‘naked eye’ detection of fluoride ions (as low as 0.1 equiv with respect to the gelator concentration), through a reversible gel–sol transition, which is associated with a color change from deep yellow to bright red.
