Various LMGs using D-gluconic acid, the ring-opened structure of D-glucono-1,5-lactone (1,5-GL), have already been developed. Song et al. have reported that D-gluconic acid derivatives with a benzylidene group at the 2,4-position hydroxy groups and an alkylamide group at the 1-position can be used as organogelators. Fang et al. have reported that D-gluconic acid derivatives with a benzylidene group at the 2,4-position hydroxy groups and a methyl ester group at the 1-position can be used as organogelators. These are derivatives of the linear D-gluconic acid and are immobilized with a benzylidene group that can control the molecular mobility of the 2,4-position hydroxy groups.
