“…Rheological studies of a soft material is extremely important in terms of its pratical applications [43][44][45][46][47][48][49][51][52][53][54][55][56][57] Amplitude-sweep experiments of the halogel 2.5 show the storage modulus, Gʹ, to be almost ~5 times larger than the respective loss modulus, Gʺ, in the linear viscoelastic regime with a yield strain value of ~5.5%, confirming the viscoelastic behavior of the halogel(Figure 3a) 43.…”

Halogen-bonding-induced self-assembly in the solution of equimolar mixtures of certain pyridyl-ended oligo p-phenylenevinylene (OPV)-derivatives with 1,4-diiodotetrafluorobenzene is reported. The mode of self-assembly, that is, cocrystallization, thixotropic gelation, or precipitation, depends strongly on the nature of chains (n-alkyl chains as a function of length or short oxyethylene chain) appended to the OPV-backbone as well as on the cooling rate of the corresponding hot solution. Single-crystal X-ray diffraction studies of the cocrystals reveal the "infinite" chain formation via C-I···N halogen-bonding interactions between the two components. In addition, multiple noncovalent interactions induce cross-links among these halogen-bonded "infinite" chains. Interestingly, the molecular packing in the "Cogel" bearing OPV-derivative with oxyethylene chains is found to be very similar to that of the cocrystal of the same.

“…The Gulf of Mexico oil spill in 2010 not only seriously damaged the marine water, animals and plants, but also was a great loss of energy [1][2][3]. Various techniques including oil skimmers, oil containment booms, in situ burning, dispersants, solidifiers and absorbents have been employed to solve the problem of oil pollution [4][5][6][7]. Amongst them, removing oil by low-cost and efficient absorbing materials is convenient and attractive, as oil pollutants can be transformed from liquid into absorbents, realizing the collection and elimination of oil from water system.…”

A New Class of Phase‐Selective Synthetic β‐Amino Acid Based Peptide Gelator: From Mechanistic Aspects to Oil Spill Recovery

The mechanistic aspects of supramolecular ordering of synthetic β‐amino acid based peptides in different organic solvents and fuel oils are reported. The peptide Boc‐cis‐ACHC‐Aib‐Phe‐OMe (Boc=tert‐butyloxycarbonyl, cis‐ACHC=cis‐2‐aminocyclohexanecarboxylic acid, Aib=α‐amino isobutyric acid, Phe=phenylalanine; 1) is able to entrap various organic solvents and oils, leading to the formation of self‐supporting gels. Spectroscopic studies confirm the turn‐type β‐sheet arrangement of peptide 1 in the gel phase. A morphology study shows that a bundle of nanofibers form from self‐assembled peptide 1. Peptide 1 is capable of entrapping organic or oil layers selectively over the aqueous layer. Furthermore, the phase‐selective gelation behavior of peptide 1 is effectively used as a model study for oil spill recovery from a biphasic mixture of oil and water.
