| Outline of Final Research Achievements |
A new hybrid macrocycle for the optical detection of Cs-137 is designed. The macrocycle is made of cucurbituril (a molecule with the shape of a pumpkin) and naphthalene. This hybrid macrocycle can sense the presence of Cs+ ions when uv-vis radiation is used. Also, the fluorescence spectra of the hybrid macrocycle show a change in intensity when the Cs+ ion binds the carbonyl groups of the macrocycle. These results indicate that the designed chemosensor can be used for the detection of Cs-137 in contaminated soils and fluids.
