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

Neethu K. Sadanandhan, Sarojam Sivakala, and Sudha J. Devaki*

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, p-p, 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.
