Disclosed are “acid-amide” calixarenes of formula (I) wherein: L is [—CH2—] or [—O—CH2—O—] and may be the same or different between each aryl group R5 is H, halogen, or C1-C10 aliphatic hydrocarbyl group, C6-C20 aryl group, any of which may optionally be substituted by one or more halo or oxo groups or interrupted by one or more oxo groups, and R5 may be the same or different on each aryl group; R1 comprises an optionally protected carboxy group; two groups out of R2, R3, and R4, are H; the one group out of R2, R3, and R4 not being H comprises an amide group. The amide group may be linked to a second calixarene to form a dimer. Also disclosed are methods of use of such calixarenes for the purposes of metal sequestration, especially of lanthanides and actinides. Also disclosed are calixarene dimer derivatives of the calixarenes of the invention. Also disclosed are processes for preparing the calixarenes and dimers
揭示了式(I)的“酸酰胺”杯芳烃,其中:L为[—CH2—]或[—O—CH2—O—],且在每个芳基之间可能相同或不同,R5为H、卤素或C1-C10脂肪烃基、C6-C20芳基,其中任何一个可能选择性地被一个或多个卤素或氧基取代或被一个或多个氧基中断,且R5在每个芳基上可能相同或不同;R1包括一个可选择性保护的羧基;R2、R3和R4中的两个基为H;R2、R3和R4中的一个不是H的基包括一个酰胺基。酰胺基可以与第二个杯芳烃连接形成二聚体。还揭示了利用这种杯芳烃用于金属螯合的方法,特别是镧系和锕系金属。还揭示了本发明的杯芳烃的杯芳烃二聚体衍生物。还揭示了制备这些杯芳烃和二聚体的方法。
