在宿主微孔钼（II）二羧酸酯（富马酸酯、对苯二甲酸酯、反式-反式-二羧酸酯和吡啶-2,5-二羧酸酯）和客体有机聚醚（聚乙二醇（PEG）和聚丙二醇（PPG））之间合成了新型包合物。络合物的形成速率取决于微孔和聚醚的形状。除钼（II）吡啶-2,5-二羧酸酯不与体积较大的PPG形成配合物外，所含聚醚的量随着分子量的增加而增加，并达到饱和量。微孔钼（II）二羧酸盐中氩的吸附量随着聚醚加入量的增加而减少。聚乙二醇对对苯二甲酸钼的13C CP/MAS NMR测定表明，聚乙二醇链包含在毛细血管中。这是一种合成超分子配合物的有效方法。
Novel inclusion complexes between host microporous molybdenum(II) dicarboxylates (fumarate, terephthalate, trans−trans-muconate, and pyridine-2,5-dicarboxylate) and guest organic polyethers (poly(ethylene glycol) (PEG) and poly(propylene glycol) (PPG)) of various molecular weights were synthesized. The rate of complex formation depends on the shapes of the micropores and polyethers. The amount of included polyethers increased with their molecular weight, and reached a saturated amount, with the exception that molybdenum(II) pyridine-2,5-dicarboxylate did not form complexes with bulky PPG. The amount of adsorbed argon in the microporous molybdenum(II) dicarboxylates decreased with increased amounts of included polyethers. The 13C CP/MAS NMR measurement of molybdenum(II) terephthalate with PEG demonstrated that PEG chains are included in the capillaries. This is an effective method for synthesizing supramolecular complexes.
