Triterpenes, an important class of plant secondary metabolites derived from C30 precursor squalene are nano-sized molecules having varied lengths of rigid and flexible parts. We have utilized these nano-sized triterpenoids as renewables in the design of molecular receptors, supramolecular architectures and functional nano-materials.1-7 Arjunolic acid, the major component of the extracts of the heavy wood of Terminalia Arjuna became the first choice for such investigations. The various derivatives of the nano-sized chiral triterpenic acid could immobilize various organic solvents at low concentrations and self-assembled in organic media to form nano-sized vesicles and nano-fibers with concomitant hardening of the media. Benzyl, (naphthyl) methyl and (anthryl) methyl arjunolate were synthesized and their gelation abilities were tested. (Naphthyl) methyl and (anthryl) methyl arjunolate formed thermo reversible transparent gels efficiently mostly with aromatic solvents while benzyl arjunolate did not form gel with any one of the aromatic solvents except cyclohexane. Electron micrographs of the xero-gels revealed nano vesicles and also fibrous network consisting of fibers of micrometer lengths and nanometer diameters
