Six new diazadibenzo-18-crown-6 ligands substituted with two each of 8-hydroxyquinoline (7), 8-amino-quinoline (attached through its C-2 or C-7 position) (12 and 13), 8-methoxyquinoline (18), 5-chloro-8-methoxyquinoline (19), and dansylamidoethyl (21) side arms were synthesized as potential metal ion chemosensors and potential reagents for the selective extraction of certain metal ions from aqueous
六个新的重氮二苯并18-18冠-6配体分别被8-羟基喹啉(7),8-氨基喹啉(通过其C-2或C-7位置连接)(12和13),8-甲氧基喹啉中的两个取代18)合成了5-氯-8-甲氧基喹啉(19)和dansylamidoethyl(21)侧臂作为潜在的金属离子化学传感器和潜在的试剂,用于从水溶液中选择性提取某些金属离子。配体7,12,13,18,和19,通过二苯并-18-冠-6(还原胺化合成5)及相应的quinolinecarboxaldehydes。双(丹西酰胺基乙基)取代的配体21通过用N-丹磺酰氮丙啶(20)处理二氮杂皇冠醚5来合成。
