摘要

A chloride anion templation methodology is utilized in the construction of novel transition-metal rhenium(I) and ruthenium(II) bipyridyl appended [2]rotaxanes. 1~H NMR spectroscopic titrations reveal the ability of the rotaxanes to selectively bind chloride over the more basic oxoanions, with the ruthenium(II) bipyridyl appended rotaxane strongly binding chloride in_30 % water. Photophysical investigations demonstrate the ability of the rotaxanes to sense anions in aqueous media, with chloride being selectively complexed, in general agreement with NMR spectroscopy determined anion binding data. Chloride anion templation is used to synthesise novel rhenium(I) and ruthenium(II) bipyridyl appended [2]rotaxanes (see figure). 1H NMR spectroscopic titrations reveal the rotaxanes are capable of binding anions in competitive aqueous solvent mixtures, with the ruthenium rotaxane strongly complexing chloride in_30 % water. Photophysical investigations demonstrate the ability of the rotaxanes to sense anions in aqueous solvent mixtures.
