Abstract:

Two crown ethers bearing anthracene aromatics were synthesized from 9,10-dibromomethyl anthracene via three steps. The host-guest binding behavior between new crown ethers and two π-electron-deficient guests was investigated by means of 1H NMR, UV-Vis spectroscopy and X-ray diffraction analysis. The results revealed that host-guest interaction between anthracene crown ethers and guests was mainly contributed by π-stacking. The association constants determined by UV-Vis spectrum. The result showed anthracene crown ethers had better binding ability than classical bezo- and naphtho-crown ethers, which indicated the introduction of anthracene aromatics could improve the host-guest binding ability of crown ethers significantly.

Key words: Anthracene, Crown ether, Host-guest binding, π-Stacking interaction
