Abstract
The synthesis and characterization of a new chiral LMWG 1 based on the axially chiral binaphthalene with two urea moieties were described. A transparent gel in cyclohexane with LMWG 1 was obtained and characterized by SEM, XRD and CD techniques. The results of 1H NMR measurement indicated that the intermolecular H-bonds and π−π interaction may be responsible for the gel formation. It was demonstrated that the gel phase could be destroyed by addition of F- due to the disruption of intermolecular H-bonds. After gel formation, modulation of the CD spectrum of 1 was observed.
