双硫脲冠醚对无机离子对的识别作用 Recognition of Bisthiourea Crown Ether to Inorganic Ion-Pair 王宇凯 WANG Yu-kai 1 2 first-author 余天祥 YU Tian-xiang 1 2 周世来 ZHOU Shi-lai 1 2 武汉大学化学与分子科学学院 武汉大学化学与分子科学学院 College of Chemistry and Molecular Sciences,Wuhan University College of Chemistry and Molecular Sciences,Wuhan University 武汉大学化学与分子科学学院,湖北,武汉,430072 武汉大学化学与分子科学学院,湖北,武汉,430072 合成了两种新的双苯基硫脲二苯并 18 冠 6冠醚（L1,L2）,研究了它们对NaH2PO4·2H2O,KH2PO4,KHSO4,KNO3,KHCO3等无机盐的识别能力,并用红外光谱、核磁共振氢谱、X 射线粉末衍射分析等方法对配合前后进行了表征.结果表明对这些无机盐而言L2的配合能力优于L1,L1与L2有类似的识别次序:KH2PO4>NaH2PO4>KHSO4>KNO3 KHCO3. Two novel bis（phenyl thiourea） DB-18-C-6（L 1 ,L 2 ） have been synthesized. The recognition of L 1 ,L 2 to NaH 2 PO 4 2H 2 O, KH 2 PO 4 , KHSO 4 , KNO 3 and KHCO 3 has been studied via IR, 1 H NMR and XRD. The data indicate that the binding capacity of L 2 is better than that of L 1 , and they bound ions with a same selectivity in the order of KH 2 PO 4 > NaH 2 PO 4 > KHSO 4 > KNO 3 KHCO 3 . 双硫脲冠醚 合成 无机离子对 识别 bisthiourea crown ether synthesis inorganic ion-pair recognition O621 2004-04-01 2021-04-01 4
