| Research Abstract |
We have synthesized (i)C2v symmetrical armed-cyclens having two kinds of aromatic rings, (ii)Cs symmetrical armed-cyclens having two kinds of aromatic rings, (iii)armed-cyclens having two chromophores as side-arms at 1- and 7- positions, and (vi) a chiral armed-cyclen having four aromatic rings.
For compound (i) : Cu^<2+> complex with the new ligand formed two-dimensional matrix. Using Ag^+ and Cu^<2+>, a linear polymer-like complex formed. Using Cu^+ and Cu^<2+>, a hexagonal two-dimensional matrix formed.
For compounds (ii) : New ligands having Cs symmetrical armed-cyclens having two kinds of aromatic rings were prepared. The X-ray structures and complexing abilities are now in progress.
For compounds (iii) : Armed-cyclens having two naphthalene units, two anthracene units, and two pyrene units were prepared. Metal induced titration experiments using ^1H NMR, UV-VIS and fluorescence spectra were occured. The results indicats that the selectivities toward metal ions depend on the chromophores as side-arms.
For compounds (vi) : Chiral armed-cyclen were prepared. Amplification of chirality were confirmed when the ligand forms a complex with Ag^+.
In conclusion, several type of new armed-cyclens have been prepared, and studied on functions and dynamics. The project is now in progress.
