The title compound, C48H60O8.3C3H7NO, is a derivative of calix[4]arene in the cone conformation, modified with distal carboxylic acid functional groups at the lower rim. A clathrate dimethylformamide (DMF) molecule is located within the calix[4]arene cone, and two DMF solvate molecules participate in hydrogen bonding with the carboxylic acid groups. Intramolecular hydrogen bonds are also formed between the OH groups and the adjacent ether groups in the partially substituted calix[4]arene.
标题化合物C48H60O8·3C3H7NO是杯[4]芳烃的一种衍生物，呈锥形构象，在下边缘带有远端羧酸官能团。一个包合物二甲基甲酰胺（DMF）分子位于杯[4]芳烃锥体内，两个DMF溶剂化物分子与羧酸基团形成氢键。在部分取代的杯[4]芳烃中，OH基团与相邻的醚基团之间也形成了分子内氢键。
