Improved synthesis and characterization of bile acid esters: Organogelation and supramolecular properties

Abstract

Bile acid esters and their derivatives hold significant interest due to their applications in fields such as supra molecular chemistry, biomedicine, and nanomaterials. This study revisits the synthesis and characterization of esters derived from cholic, deoxycholic, and lithocholic acids using short-chain alcohols in combination with microwave-assisted heating. The synthesized esters were analyzed for their potential as gel-forming agents, and their organogelation properties were evaluated. Microwave-assisted synthesis offers rapid and efficient esteri f ication, leading to high yields with improved selectivity. The organogels were characterized through techniques such as differential scanning calorimetry (DSC) and scanning electron microscopy (SEM), revealing distinct structural and thermal properties. The study highlights the potential of these bile acid esters in materials science and supramolecular chemistry, contributing to the development of novel functional materials.
