Light-Responsive Arylazopyrazole Gelators: From Organic to Aqueous Media and from Supramolecular to Dynamic Covalent Chemistry

Versatile photoresponsive gels based on tripodal low molecular weight gelators (LMWGs) are reported. A cyclohexane-1,3,5-tricarboxamide (CTA) core provides face-to-face hydrogen bonding and a planar conformation, inducing the self-assembly of supramolecular polymers. The CTA core was substituted with three arylazopyrazole (AAP) arms. AAP is a molecular photoswitch that isomerizes reversibly under alternating UV and green light irradiation. The E isomer of AAP is planar, favoring the self-assembly, whereas the Z isomer has a twisted structure, leading to a disassembly of the supramolecular polymers. By using tailor-made molecular design of the tripodal gelator, light-responsive organogels and hydrogels were obtained. Additionally, in the case of the hydrogels, AAP was coupled to the core through hydrazones, so that the hydrogelator and, hence, the photoresponsive hydrogel could also be assembled and disassembled by using dynamic covalent chemistry.

A metal-organic framework gel with Cd2+ derived from only coordination bonds without intermolecular interactions and its catalytic ability

A cyclohexane-based ligand (1) as a triconnected linker forms a supramolecular gel in the presence of transition metal ions, particularly Cd2+ and Zn2+. 1 can also be gelated with cadmium counter ions such as NO3-/su

Design, synthesis, and solution behaviour of small polyamines as switchable water additives

The practice of adding salt to water to induce salting out of contaminants or to break emulsions and suspensions is generally avoided industrially because of the expense of the necessary treatment of the salty water afterwards. However, the use of switchable water, an aqueous solvent with switchable ionic strength, allows for reversible generation and elimination of salts in aqueous solution, through the introduction and removal of CO2. In the effort to improve the efficiency of these switchable salts, a physical study modeling their reactivity and solution behaviour has been performed, resulting in a set of design principles for future switchable water additives. The resulting polyamines synthesized using this template show the highest efficiency recorded for a switchable water additive. The Royal Society of Chemistry 2012.

Holographic investigations of azobenzene-containing low-molecular-weight compounds in pure materials and binary blends with polystyrene

This paper reports on the synthesis and the thermal and optical properties of photochromic low-molecular-weight compounds, especially with respect to the formation of holographic volume gratings in the pure materials and in binary blends with polystyrene. Its aim is to provide a basic understanding of the holographic response with regard to the molecular structure, and thus to show a way to obtain suitable rewritable materials with high sensitivity for holographic data storage. The photoactive low-molecular-weight compounds consist of a central core with three or four azobenzene-based arms attached through esterification. Four different cores were investigated that influence the glass transition temperature and the glass-forming properties. Additional structural variations were introduced by the polar terminal substituent at the azobenzene chromophore to fine-tune the optical properties and the holographic response. Films of the neat compounds were investigated in holographic experiments, especially with regard to the material sensitivity. In binary blends of the low-molecular-weight compounds with polystyrene, the influence of a polymer matrix on the behavior in holographic experiments was studied. The most promising material combination was also investigated at elevated temperatures, at which the holographic recording sensitivity is even higher. Fast holographic response: The formation of volume gratings in photochromic low-molecular-weight compounds is investigated. The compounds consist of a central core with azobenzene-based arms attached through esterification (see image). Films of the neat compounds and binary blends of the low-molecular-weight compounds with polystyrene are investigated in holographic experiments.

C3-Symmetric, amino acid based organogelators and thickeners: a systematic study of structure-property relations

A class of C3-symmetric amino acid based organogelators and thickeners featuring a rigid core have been developed. Structural variation yielded a number of compounds, the aggregation behaviour and resulting aggregates and gels of which were studied by FTIR spectroscopy, dropping ball measurements, differential scanning calorimetry and transmission electron microscopy. These studies showed that the nature of the core unit, the type of hydrogen-bonding units and the applied amino acids have a strong influence on the interactions, resulting in large differences in aggregation properties, thermal stability and morphology between the various compounds. The results provide a basis for a better understanding of the relation between aggregate/gel properties and molecular structure. The structural variation available for these compounds allows fine-tuning of the gelators with respect to aggregation behaviour and gel properties.

Gelling agents

The invention relates to a novel class of gelling agents, to a process of preparing said agents, to the use of said agents to prepare gels, and to the gels thus obtained. A gelling agent or thickener according to the invention comprises a rigid core which is functionalized with three amino acid ester or amide groups by means of an amide or urea linkage. It may be used to gelate or thicken numerous solvents.
