Tweaking the Organization of Liquid Crystallinity and Molecular Gelation in Cholesterol Tagged Cardanol by Self‐Assembly

Abstract

This paper describes the effect of unsaturation, solvent, concentration and temperature on the specific modes of packing and the formation of supramolecular architectures in cholesterol tagged cardanol, 3‐pentadecyl phenol. Influences were investigated using various microscopic techniques, UV‐Vis spectroscopy, emission spectroscopy, Circular Dichroism (CD) spectroscopy, X‐Ray Diffraction (XRD) and rheometry. Results revealed that the driving force for the self‐assembly is the combined effect of the shape of molecules, specific intermolecular interactions such as chiral‐chiral, π‐π, electrostatic layer by layer stacking and molecule–solvent interactions among the molecular layers. Based on the results obtained, a plausible mechanism for the formation of self‐assembled architectures from one‐dimensional nanowire to two‐dimensional micro sheets and three‐dimensional spherulites/helical fibrillar networks is presented.

Modulating nanostructure morphology and mesomorphic properties using unsaturation in cardanol–azo benzenes

“…6 The kink in the alkyl chains would affect the packing of molecules/morphology of the assemblies, and would alter properties such as fluidity, liquid crystallinity, etc. 6,7 In this regard, we investigated designing low temperature liquid crystalline (LC) materials using cardanol, considering that the unsaturated chain can induce packing disorder in LC materials, and can lower the transition temperature. 7…”
