were explored. In addition to the previously reported ligands 2,2′-(2-methyl-2-(pyridin-2-yl)propane-1,3-diyl)bis(azanediyl)bis(methylene)diphenol (H2L1) and 6,6′-(2-methyl-2-(pyridin-2-yl)propane-1,3-diyl)bis(azanediyl)bis(methylene)bis(2,4-di-tert-butylphenol) (H2L1-tBu), four new ligands were synthesized: 6,6′-(2-methyl-2(pyridine-2-yl)propane-1,3-diyl)bis(azanediyl)bis(methylene)bis(2,4-dibromophenol)
探索了一系列潜在的五齿吡啶基双(氨基酚)配体的配体结合偏好。除了先前报道的配体2,2'-(2-甲基-2-(吡啶-2-基)丙烷-1,3-二基)双(氮杂二基)双(亚甲基)二酚(H 2 L 1)和6,6'-(2-甲基-2-(吡啶-2-基)丙烷-1,3-二基)双(氮杂二基)双(亚甲基)双(2,4-二叔丁基苯酚)(H 2 L 1- t Bu),合成了四个新的配体:6,6'-(2-甲基-2(吡啶-2-基)丙烷-1,3-二基)双(氮杂二基)双(亚甲基)双(2 ,4-二溴苯酚)(H 2 L 1-Br),6,6'-(2-甲基-2(吡啶-2-基)丙烷-1,3二基)双(氮杂二基)双(亚甲基)双(2-甲氧基苯酚)(H 2L 1-MeO),2,2'-(2-甲基-2(吡啶-2-基)丙烷-1,3二基)双(氮杂二基)双(亚甲基)双(4-硝基苯酚)(H 2 L 1- NO 2)和2,2'-(2-苯基丙烷-1,3-二基)双(氮杂二基)双(亚甲基)二酚(H
