Mixed amide/amine macrocyclic anion hosts of varying sizes and with different amine substituents have been synthesized and characterized. Host 2, containing a 28-membered ring and secondary amines, has shown selectivebinding for HSO4− over other oxo anions and halides in DMSO-d6 using NMR titrations. Crystal structures of SO42−, HPO42−, H2PO4−, and H2P2O72− with the 28-membered ring hosts indicate
已经合成并表征了大小不同且具有不同胺取代基的混合酰胺/胺大环阴离子主体。主机2,含有28元环胺和仲胺,已经显示出选择性结合HSO 4 -比其它含氧阴离子和卤化物在DMSO- d 6使用NMR滴定。SO的晶体结构4 2-,HPO 4 2-,H 2 PO 4 - ,和H 2 P 2 ö 7 2-具有28个环的环主体的化合物根据N-取代基指示不同的大环构象。阴离子亲和力似乎与大环构象有关。
