“…The reaction was completed by the removal of 1.8 mL of water. Then the reaction mixture was distilled under vacuum to complete removal of the unreacted materials and solvent to afford the desired nonionic amphiphiles [19] which were denoted as SBG-10, SBG-12, SBG-16, SBG-18 and SBG-oleate, Scheme 2.…”

“…As for the absorption spectrum of CH-PY in ethanol solution, the absorption peaks appeared at 208, 283, 388, and 447 nm, which could be ascribed to the local π–π* transition of aromatic ring and charge transfer of conjugated structure in spacer [64,65]. For the spectra of xerogels from different solvents, the latter two absorption bands shifted noticeably to the ranges of 398–402 and 465–482 nm, respectively.…”

The self-assembly of small functional molecules into supramolecular structures is a powerful approach toward the development of new nanoscale materials and devices. As a class of self-assembled materials, low weight molecular organic gelators, organized in special nanoarchitectures through specific non-covalent interactions, has become one of the hot topics in soft matter research due to their scientific values and many potential applications. Here, a bolaform cholesteryl imide compound with conjugated aromatic spacer was designed and synthesized. The gelation behaviors in 23 solvents were investigated as efficient low-molecular-mass organic gelator. The experimental results indicated that the morphologies and assembly modes of as-formed organogels can be regulated by changing the kinds of organic solvents. Scanning electron microscopy and atomic force microscopy observations revealed that the gelator molecule self-assemble into different aggregates, from wrinkle and belt to fiber with the change of solvents. Spectral studies indicated that there existed different H-bond formations between imide groups and assembly modes. Finally, some rational assembly modes in organogels were proposed and discussed. The present work may give some insight to the design and character of new organogelators and soft materials with special structures.

“…For example, we previously designed some Schiff base compounds containing naphthyl group and investigated their supramolecular assemblies at the air=water interface. [24] We found that due to the different substitutions in the amphiphilic Schiff bases, different molecular orientations in the LB films were obtained.…”

Some single chain Schiff bases amphiphiles with different substituted headgroups have been designed and their interfacial phase behaviors and coordination with Cu(II) ions were investigated. It has been found that depending on the size of aromatic headgroups, the formed nanostrucures showed obvious differences, indicating different aggregation behaviors in the Langmuir-Blodgett films. The spreading Cu(II)-coordinated films could be transferred and subsequently characterized by spectral methods and morphological measurement. In addition, during the coordination process of ligand with Cu(II) ions in organized molecular films, some conformational change of long alkyl chains was observed. The present work showed clearly the headgroup effect of amphiphiles on regulating the aggregation behaviors in Langmuir-Blodgett films.
