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.

Low molecular weight organogelators derived from threefold symmetric tricarbamates

A group of new low molecular weight organogelators based on threefold symmetric tricarbamate were synthesized and characterized. The tricarbamates with long alkyl chains were able to gelate a wide range of polar and nonpolar organic solvents such as aceto

De Novo Tailoring Pore Morphologies and Sizes for Different Substrates in a Urea-Containing MOFs Catalytic Platform

To better understand the structure-catalytic property relationship, a platform of urea-containing MOFs with diverse topologies as hydrogen-bonding (H-bond) catalyst has been well established in the present work. During the construction of MOFs, we proposed a new strategy called the isoreticular functionalization approach in which the desired topological net is first considered as a blueprint, and then two predesigned functionalized polydentate ligands link to four different metal clusters by de novo routes to achieve the MOFs with expected pore structure and catalytic sites. By means of this strategy, we successfully synthesized four programmed MOFs (named as URMOF-1-4) with diverse topologies, pore morphologies, and sizes and distribution of active sites. Subsequently, we systematically investigated the Friedel-Crafts reactions of 1-methylpyrrole or 1-methylindole with nitroalkene derivatives with diverse sizes to assess the catalytic properties of the above-mentioned URMOFs. These four URMOFs can act as reusable H-bond catalysts and show varied catalytic capacities and size-selectivity properties. Most significantly, the open morphologies of pores, large channels in the framework, and effective distribution of active sites on the wall of the channel are proved to facilitate catalysis. This urea-containing MOF catalytic platform provides new insight into the catalytic properties of MOFs with the same kind of active sites but diverse topologies, pore morphologies, and sizes and distributions of catalytic sites.

Preferred Binding of Carboxylates by Chiral Urea Derivatives Containing α-Phenylethyl Group

An efficient, simple protocol for the synthesis of a new family of chiral ureas 1 – 4 is described. The binding properties of 1 – 4 toward different anion (acetate, benzoate, fluoride, and chloride) have been studied by1H-NMR titration and have been observed in the case of 4 is a selective receptor for acetate. The theoretical calculation M06/6-311+G(d,p) helped us explain the binding properties observed. The most interesting observation is that this calculated structure is consistent with expected, based on the concept of allylic 1,3-strain (A1,3strain). When chiral caboxylates were studied, urea 1 was the best in discriminating between enantiomers.

Urea-based porous organic frameworks: Effective supports for catalysis in neat water

Two urea-based porous organic frameworks, UOF-1 and UOF-2, were synthesized through a urea-forming condensation of 1,3,5-benzenetriisocyanate with 1,4-diaminobenzene and benzidine, respectively. UOF-1 and UOF-2 possess good hydrophilic properties and high scavenging ability for palladium. Their palladium polymers, PdII/UOF-1 and PdII/UOF-2, exhibit high catalytic activity and selectivity for Suzuki-Miyaura cross-coupling reactions and selective reduction of nitroarenes in water. The catalytic reactions can be efficiently performed at room temperature. Palladium nanoparticles with narrow size distribution were formed after the catalytic reaction and were well dispersed in UOF-1 and UOF-2. XPS analysis confirmed the coordination of the urea oxygen atom with palladium. SEM and TEM images showed that the original network morphology of UOF-1 and UOF-2 was maintained after palladium loading and catalytic reactions. Feeling supportive? Two urea-based porous organic frameworks were prepared by a facile urea-forming condensation and can serve as effective supports in palladium-catalyzed Suzuki-Miyaura cross-coupling reactions and reduction of nitroarenes in water. The reactions can even be efficiently performed at room temperature. The original morphology of the urea-based frameworks was maintained after the catalytic reactions.

(Figure Presented) Five new highly functionalized cyclobutane containing C3-symmetric peptide dendrimers have been synthesized through a convergent approach from 1,3,5-trisubstituted benzene and chiral λ,ε-amino diacid derivatives as well as a λ-tetrapeptide. The first example of the synthesis of N-centered amides by using 1,3,5-triaminobenzene and a carboxylic acid is reported.

Safer conditions for the Curtius rearrangement of 1,3,5- benzenetricarboxylic acid

A rapid method to prepare 1,3,5-triaminobenzene and its derivatives is the tris-Curtius rearrangment of 1,3,5-benzenetricarboxylic acid. The hazards associated with the acyl azide route are minimized by using 1,2-dichloroethane as solvent. A second method that avoids acyl azide preparation uses diphenylphosphoryl azide to yield the tricarbamate in one step. Copyright Taylor & Francis Group, LLC.
