| Research Abstract |
Nitrosonium ions are one of the main causes for green-house effect and acid rain. On the other hand they play a critical role in biological system. Supramolecular chemistry which could produce novel functions by combining small molecules using non-covalent bondings has always attracted a major interest. The purposes of this research are preparation of the box-shaped host molecules showing the metal luminescence and investigation of the ability to bind nitrosonium ions selectively. Especially the system in which metal luminescence can be observed when binding a nitrosonium ion is developed. The host compound having the porphyrin unit and ligand part was prepared, then the europium complex was synthesized. The structure of this novel complex was examined by their spectral properties. They show a large spectral change when they bind the amine derivative. When they bind the C60, their fluorescence emissions decrease. And energy transfer was confirmed between the porphyrin units and C60. The details are now under investigation. The cyclophane compound consisting of the porphyrin units were also prepared. They exhibit a unique dynamic structure. It has been found out that this cyclophane assume the syn-structure which can provide the cleft binding the guest molecule inside of it. They have shown a strong binding for amine derivatives. We also prepared the europium complexes having the amide units affording the hydrogen sites. The structure of theses complexes depends on the length of the alkyl chains of the ligands. Selective binding is now investigated using the hydrogen bondings.
