结合三价镧系离子和对磺化杯[4]芳烃的新型结构基序已得到验证，这些结构基序来自含有或不含有杯芳烃潜在主体分子（特别是18 - 冠 - 6、1 - 氮杂 - 18 - 冠 - 6和穴醚[2.2.2]）的溶液。其中包括形成双层片状结构的配位聚合物，以及铈离子（Ce³⁺）前所未有的“摩天轮”和“分子胶囊”组合结构，该结构包含了两种先前报道的与这类化学相关的结构基序，分别对应于镧系中铈元素左右两侧的元素。
New structural motifs incorporating trivalent lanthanoid ions and p-sulfonatocalix[4]arene, derived from solutions with or without potential host molecules for the calixarene, notably 18-crown-6, 1-aza-18-crown-6, and cryptand[2.2.2], have been authenticated. These include coordination polymers which form bi-layer sheet structures and an unprecedented combined ‘ferris wheel’ and ‘molecular capsule’ structure for Ce3+ which incorporates two previously reported structural motifs associated with this type of chemistry, respectively for elements to the left and right of cerium in the lanthanide series.
