新型共价大环化合物 hmcyCuc6 已被合成，并报道了其四种假多晶型物。 HmcyCuc6在晶体生长中对CH2Cl2、CHCl3和CCl4具有高度选择性，hmcyCuc6对这些溶剂分子的选择性可能与溶剂分子的对称性有关。此外，可以通过改变结晶溶剂系统来简单地控制四种假多晶型。据我们所知，葫芦[n]脲同系物的假多态性是首次报道。
Novel covalent macrocycle, hmcyCuc6, has been synthesized and its four pseudopolymorphs were reported. HmcyCuc6 is highly selective to CH2Cl2, CHCl3, and CCl4 in the crystal growth, and the selectivity of the hmcyCuc6 toward these solvent molecules may be related to the symmetry of the solvent molecules. In addition, four pseudopolymorphs can be simply controlled by changing the crystallization solvent system. To our best knowledge, the pseudopolymorphism of the cucurbit[n]uril homologues is reported for the first time.
