| Abstract | NMR Spectroscopy and FAB mass spectrometry demonstrate that the 38-crown-10 (1/5DN38C10) and 35-crown-9 (1/5DN35C9) ethers incorporating two 1,5-di-naphtho units form 1:1 complexes with the Paraquat [PQT]2+ and Diquat [DQT]2+ dications in solution. In the solid state, the [PQT.1/5DN38C10]2+ complex is stabilised by face-to-face (π/π charge transfer) interactions between the naphtho and bipyridinium rings, whereas the free 1/5DN35C9 receptor features a classic edge-to-face (Hδ+/π electrostatic) interaction between its two naphtho rings. © 1987. |
