Triterpenes, the C30 subset of the major plant secondary metabolite terpenes, are promising in this respect because of their abundant skeletal types and included functional groups.1 Moreover, the extended lengths of triterpenoids, whether acyclic, monocyclic, or rigid pentacyclic structures, are in the nanometer range. As such, they may be useful building blocks for nano-science and nano-technology applications.2 Arjunolic acid a 6-6-6-6-6 pentacyclic triterpenoid, arjunolic acid (1), from Terminalia Arjuna22 and discovered that an arjunolic acid-derived molecule forms thermochromic organogels.3 Benzyl and (4-nitrophenyl) methyl arjunolate were synthesized and their gelation abilities were tested. (4-nitropheyl)methyl arjunolate formed thermo reversible transparent gels efficiently mostly with aromatic solvents while benzyl arjunolate did not form gel with any of the solvents. Electron micrographs of the xero-gels revealed a fibrous network consisting of fibers of micrometer lengths and nanometer diameters.
