The synthesis, characterisation, and electrochemical studies of dicopper(II) complexes [Cu2L1][ClO4]2·nH2O of the macrocycle 7,11;19,23-dimetheno-9,21-dimethyl[1,5,13,17]-tetra-azacycloicosa-5,7,9,12,17,19,21,24-octaene-25,26-diol (H2L1), and of some 6,12,18,24-substituted (Me4; Prn4; Ph4; Ph, Me, Ph, Me) derivatives have been carried out. These compounds undergo sequential one-electron transfers at
大环7,11; 19,23-dimetheno-9,21-dimethyl [1 ]的Dicopper(II)配合物[Cu 2 L 1 ] [ClO 4 ] 2 · n H 2 O的合成,表征和电化学研究,5,13,17] -tetra-azacycloicosa-5,7,9,12,17,19,21,24-辛烯-25,26-二醇(H 2 L 1),以及大约6,12,18已经进行了24取代的(Me 4; Pr n 4; Ph 4; Ph,Me,Ph,Me)衍生物的制备。这些化合物在两个不同的电位上经历顺序的单电子转移。对于所有这些化合物,除了[Cu 2 L 1] [ClO 4 ] 2 ·2H 2 O,使用悬挂式汞滴电极在乙腈介质中已观察到两个可逆或几乎可逆的还原步骤。在[Cu 2 L 1 ] [ClO 4 ] 2 ·2H 2 O的情况下,第二对由于吸附现象或二次电极反应的存在而变得模糊。
