摘　　要：对叔丁基杯[4]芳烃直接与1,4-二氯-2-丁炔反应,一步制备了单炔基单桥联双杯[4]芳烃和单炔基双桥联双杯[4]芳烃,并证实单桥联双杯[4]芳烃是双桥联双杯[4]芳烃的中间产物.经1HNMR,13CNMR和ESI-MS分析证实了产物的结构.ESI-MS结果表明两种产物对DMF和H2O有不同的包合能力.Single 2-butyne-bridged and double 2-butyne-bridged biscalix[4]arenes were prepared directly by the reaction of p-tert-butylcalix[4]arene with 1,4-dichloro-2-butyne using K2CO3 as a base in acetonitrile. It was found that the double 2-butyne-bridged biscalix[4]arene was formed via 2-butyne-single bridged biscalix[4]arene. Their structures were characterized by ^1H NMR, ^13C NMR and ESI-MS. They exhibited different complexion ability towards DMF and H2O molecule.
