Abstract
We have been synthesized the acyl semicarbazide derivatives (1-3) bearing aliphatic moieties, which formed a gel in hexane and cyclohexane. These cyclohexane gels showed the enhancement of the fluorescent intensity. 1H-NMR and FT-IR spectroscopy studies revealed that intermolecular hydrogen bonding formation plays an important role for the formation of the gels. Sacnning electron microscopy (SEM) measurements demonstrated that the aggregation behaviors of the compounds are greatly affected by the structure of the linkers. SEM images of the xerogel showed that 1/cyclohexane possesses a layered structure. For 2/cyclohexane system, the xerogel is characterized by fibrous structures.
