Cryptophane-E was synthesized from vanillin by a three-step method, and its absorption and fluorescence spectroscopic properties were determined. Two absorption bands at about 245–260 and 280–290nm were observed for cryptophane-E and the fluorescence emission maxima were at 320–330nm depending on the solvent used. The interaction of cryptophane-E with CHCl 3 was studied in detail by absorption...
Cryptophane-A was synthesized from vanillin by a three-step method and its spectroscopic properties in different organic solvents were determined. Two absorption bands at about 240–250 and 280–290nm were observed for cryptophane-A. A fluorescence emission peak was obtained at 320–330nm using a solution of ∼10 −5 M cryptophane-A. The interaction of cryptophane-A with chlorinated compounds CH...
