Functional self‐assembled lipidic systems derived from renewable resources

Abstract

Self-assembled lipidic amphiphile systems can create a variety of multi-functional soft materials with value-added properties. When employing natural reagents and following biocatalytic syntheses, self-assembling monomers may be inherently designed for degradation, making them potential alternatives to conventional and persistent polymers. By using non-covalent forces, self-assembled amphiphiles can form nanotubes, fibers, and other stimuli responsive architectures prime for further applied research and incorporation into commercial products. By viewing these lipid derivatives under a lens of green principles, there is the hope that in developing a structure–function relationship and functional smart materials that research may remain safe, economic, and efficient.

Unique Photophysical Behavior of Coumarin-Based Viscosity Probes during Molecular Self-Assembly

“…19 This compound exemplifies a vast family of amphiphilic organogelators bearing a highly polar sugar core and at least one long partially hydrophobic alkyl chain. 32,33 R8 possesses a minimum gelation concentration of 0.46 wt % in toluene, and a temperature of gelation at 1.0 wt % (w/v) of 45–47 °C. Optically clear gels can be formed through thermoreversible gelation (Figure 2b).…”

Fettsäuren und Fettsäurederivate als nachwachsende Plattformmoleküle für die chemische Industrie

“…Synthetische Umwandlungen für die Valorisation von Fettstoffen wurden kürzlich zusammenfassend dargestellt, [9] ebenso wie katalytische Ansätze für die Herstellung von Monomeren aus erneuerbaren Ressourcen, vor allem Fetten und Ölen, [10] und funktionale selbstorganisierende Lipidsysteme aus nachwachsenden Rohstoffen. [11] 3.1. Reduktion der Carboxygruppe Die Nutzung von Fetten und Ölen als Kraftstoff und die notwendige Verbesserung der Kraftstoffeigenschaften stimulierten eine Vielzahl an Studien über ihre katalytische Deoxygenierung zu Alkanen und Alkenen.…”

Sustainable sorbitol-derived compounds for gelation of the full range of ethanol–water mixtures

“…1 Within this area, a contemporary challenge is to target existing sustainable feedstocks for the synthesis of supramolecular gelators. 2,3 The incorporation of environmentally friendly approaches guided by the principles of green chemistry can give alternatives to the more conventional chemical designs, reducing or eliminating the use of hazardous and toxic solvents. 4,5 A wide range of naturally occurring molecular motifs including polysaccharides (alginates 6 and carrageenans 7 ), ureas, 8 sugars, [9][10][11] steroids, 12 peptides 13 , acids (for example gallic acid derivatives [14][15][16] ) and other naturally occurring compounds have proven their potential as gelators.…”
