| Research Abstract |
Diacylcarbohydrazide derivatives were synthesized and their anion binding properties were investigated by using UV-vis spectroscopy in MeOH and MeOH/H_2O. Diacylcarbohydrazide derivatives selectively recognized cyanide anion through reversible formation of anion-receptor adducts that stabilized by intramolecular hydrogen bondings. The carbohydrazide derivatives bearing a aliphatic moieties were synthesized and the derivatives showed good gelation ability for various organic solvents. SEM study reveals that fiber-like or sheet-like network were gained from self-assmblingof carbohydrazide derivatives. Based on VT-NMR and IR spectral absorption investigations, the gel materials were generated from self-assembly by cooperative H-bonding and van der Waals. An organo gel of the derivatives became a homogeneous solution in response to the addition of cyanide anions.
