Abstract
This paper introduces a new metallohydrogel precursor that offers a peculiar gelation response to Co(2+) at pH 7-8. It is notable that the stability of this metallohydrogel is significantly dependent on its enantiomeric purity. In addition to the expected multi-stimuli responsive properties, including thixotropy, as well as re-assembly properties on adding HCl, this metallohydrogel possesses excellent self-healing behavior, which is uncommon in low-molecular-weight gelators. Electron microscopy (EM) studies revealed that the cryodried remains of this gel presented as well an organized three dimensional (3D) network of fibrils. This interesting metallohydrogel shows potential for developing new soft materials with drug delivery and catalysis properties.

Abstract
We report on the use of a phosphatase to assist the formation of leaf-like structures and a supramolecular hydrogel with an ultra-low minimum gelation concentration. The compound can gel water at a minimum gelation concentration of 0.01 wt%, which is the lowest gelation concentration reported up to now. The images obtained by transmission electron microscopy (TEM) reveal the existence of leaf-like structures serving as the matrix of the hydrogels. The stability of the hydrogels was studied and emission spectra were used to get information about the molecular packing in the leaf-like structures. Since lowering the concentration of the gelator decreases the toxicity of the resulting hydrogels, ultra-low concentration gels have potential uses as biocompatible biomaterials for, e.g., cell cultures, tissue engineering, and drug delivery.

Abstract
The creation of stimuli-responsive materials offers considerable challenges in the area of material science. The use of light as an external stimulus has particular advantages because it can bring about rapid transformations in remote regions in a very precise manner. Naturally occurring photoresponsive systems provide the motivation for developing corresponding artificial systems using molecular self-assembly to address issues such as quantum efficiency, selectivity, and amplification. A practical strategy for developing photoresponsive materials is to utilize molecules that can undergo considerable change in shape on photoisomerization. Although the photoisomerization of polyenes between their linear all-trans isomer and bent cis isomers has been extensively investigated in solution and in organized media because of its relevance to naturally occurring photoresponsive systems, its use in developing artificial photoresponsive systems has not been well explored. This feature article provides an overview of photoresponsive soft materials such as liquid crystals and gels with special emphasis on our recent studies related to the use of the butadiene chromophore for the design of such materials. The role of molecular self-assembly in controlling the photochemical and photophysical properties of these molecules is also discussed.

Abstract
Compound 1 containing cholesteryl and maleimide units can gel a few organic solvents such as cyclohexane. It is interesting to note that the gel-sol transition can be triggered by addition of trace amounts of thiol and triethylamine. In this regard, we successfully demonstrate the proof of principle for designing chemoresponsive gels by incorporating the reactive groups into the gelators. Additionally, the Michael adducts 2 and 3 were prepared. Compounds 2 and 3 can also gel several organic solvents. The results also show that slight molecular structural variation has a large effect on the gelation ability of the compound. These organogels were characterized with SEM, AFM, CD, and XRD. Interestingly, gelation-induced CD spectra were observed for gels of 1, 2, and 3.

Abstract
It is likely that nanofabrication will underpin many technologies in the 21st century. Synthetic chemistry is a powerful approach to generate molecular structures that are capable of assembling into functional nanoscale architectures. There has been intense interest in self-assembling low-molecular-weight gelators, which has led to a general understanding of gelation based on the self-assembly of molecular-scale building blocks in terms of non-covalent interactions and packing parameters. The gelator molecules generate hierarchical, supramolecular structures that are macroscopically expressed in gel formation. Molecular modification can therefore control nanoscale assembly, a process that ultimately endows specific material function. The combination of supramolecular chemistry, materials science, and biomedicine allows application-based materials to be developed. Regenerative medicine and tissue engineering using molecular gels as nanostructured scaffolds for the regrowth of nerve cells has been demonstrated in vivo, and the prospect of using self-assembled fibers as one-dimensional conductors in gel materials has captured much interest in the field of nanoelectronics.
