The Effect of Branched Alkyl Chain Length on the Properties of Supramolecular Organogels from Mono- N-Alkylated Primary Oxalamides. Gels 2022; 9:gels9010005.

Abstract
Mono-N-alkylated primary oxalamide derivatives with different sized branched alkyl tail-groups were excellent low molecular weight gelators for a variety of different organic solvents with different polarities and hydrogen-bonding abilities. Solvent-gelator interactions were analyzed using Hansen solubility parameters, while 1H NMR and FTIR spectroscopy were used to probe the driving forces for the supramolecular gelation. The molecular structures of the twin tail-groups did not significantly affect the supramolecular gelation behavior in different solvents. However, for select solvents, the molecular structures of the tail-groups did have a significant effect on gel properties such as the critical gelator concentration, thermal stability, gel stiffness, gel strength, network morphology, and molecular packing. Finally, metabolic activity studies showed that the primary alkyl oxalamide gelators had no effect on the metabolic activity of mouse immune cells, which suggests that the compounds are not cytotoxic and are suitable for use in biomedical applications.

Abstract
Chirality, as a fundamental symmetry property, plays an important role in molecular assembly in the solid state, impacting upon the properties and performance of organic materials. Here, heterochiral assembly was observed upon a binaphthol-based axially chiral material in the thin film state, where the heterochiral assemblies of racemic mixtures exhibit superior crystallization behavior and film morphologies than their homochiral counterparts. Additionally, a dramatic increase (nearly 2 orders of magnitudes) in electronic mobility was obtained upon switching the active layers of organic thin-film transistors from homochiral assemblies to heterochiral assemblies. This work not only gives insights into the structure-aggregation property relationships of axially chiral self-assemblies but also offers new opportunities for novel organic soft materials.

Abstract
A series of 13 enantiopure aryl benzyl sulfoxides () with different substituents on the two aromatic rings has been previously analyzed by means of electronic circular dichroism (CD) spectroscopy. Most of these compounds are crystalline and their X-ray structure is established. For almost one-half of the series, CD spectra measured in the solid state were quite different from those in acetonitrile solution. We demonstrate that the difference is due to strong exciton couplings between molecules packed closely together in the crystal. The computational approach consists of time-dependent density functional theory (TDDFT) calculations run on "dimers" composed of nearest neighbors found in the lattice. Solid-state CD spectra are well reproduced by the average of all possible pairwise terms. The relation between the crystal space group and conformation, and the appearance of solid-state CD spectra, is also discussed.
