摘　　要：通过3 溴甲基苯甲酸乙酯与杯(4)芳烃反应,制得一新的杯(4)芳烃衍生物,经元素分析,红外,1H、13CNMR确定了它的结构.晶体结构分析表明该衍生物的乙基可连续地被包合到相邻杯(4)芳烃骨架的空腔中,依靠CH π相互作用,形成二维超分子.By the reaction of (3-bromomethyl)ethyl benzoate with calix(4)arene, a new o-disubstituted calyx(4) arene derivative was synthesized. The product was confirmed by elemental analysis, IR, ()^(1)H and ()^(13)C NMR. The crystal structure was determined by X-ray crystallographic analysis, which clearly revealed that the ethyl substituents are consecutively included intermolecularly into the adjacent calix backbone cavities by CH-π interactions, thus giving rise to a two dimensional supramolecule.
