Two series of macrocyclic dicopper(II) complexes of stoicheiometry [Cu2L][ClO4]2·2H2O have been synthesized and characterized. Compounds belonging to series (1) are derived from the 6,12,18,24-substituted (H,H,Me,Me; H,H,Me,Ph; Me,Me,Me,Ph; Me,Me,Ph,Ph) macrocycie 7,11;19,23-dimetheno-9,21-dimethyl-1,5,13,17-tetra-azacyclotetracosa-5,7,9,12,17,19,21,24-octaene-25,26-diol (H2L). Complexes belonging to
合成并表征了两类化学计量比为[Cu 2 L] [ClO 4 ] 2 ·2H 2 O的大环双铜(II)配合物。属于系列(1)的化合物衍生自6,12,18,24-取代的(H,H,Me,Me; H,H,Me,Ph; Me,Me,Me,Ph; Me,Me,Ph ,Ph)macrocycie 7,11; 19,23-dimetheno-9,21-dimethyl-1,5,13,17-tetra-azacyclotetracosa-5,7,9,12,17,19,21,24-octaene- 25,26-二醇(H 2 L)。属于系列(络合物2)都与那些系列(1)通过更换两个-CH的由-CH N-键2-NH-基团和含有两个带有6,12-取代基H,H的甲亚胺键的链段;我,我;我,博士;博士 这些化合物的电化学已在MeCN和CH 2 Cl 2溶剂中使用铂和玻璃碳电极进行了研究。在所有情况下,循环伏安图均显
