On the Mechanism of Self-Assembling Chiral Gelators

DOI

Organogelators are small molecules that self-associate into extensive network structures. Our interest lies in a homologous series of such gelators, the bis-(α,β-dihydroxy diester)s. These are able to gel a wide range of disparate liquids (one of the few gelators able to do so) - fluorinated liquids, organics through to water/ethanol mixtures. We are calling this material an "omnigelator". The macroscopic structure formed in a range of liquids has been quantified on LOQ. The presence of stereogenic centres inherent in the α,β-dihydroxy diester geometry seems to be an essential requirement for the thermoreversible gelation. This is thought to be driven by hydrogen bonding between the bis-diester end-groups. We propose to verify this hypothesis by observing the spectroscopic differences of the gelator when pure, non-gelled and in a gelled state .
