of ten 5-formazanyl copper(II) complexes in toluene solutions have been observed at room temperature and at that of liquidnitrogen. The ESR(g⁄⁄ and A⁄⁄) and bonding(α2) parameters of the copper ion were greatly affected by substituting several groups at the ortho position of 1-phenyl ring of formazan. Based on these results, the complexes are classified into three groups: Group I, in which A⁄⁄\simeq0
已在室温和液氮下观察到十种 5-甲脒基铜 (II) 配合物在甲苯溶液中的电子自旋共振 (ESR) 光谱。通过在甲臜的1-苯环邻位上取代几个基团,铜离子的ESR(g⁄⁄和A⁄⁄)和键合(α2)参数受到很大影响。基于这些结果,复合物被分为三组:第一组,其中 A⁄⁄\simeq0.012–0.013 cm-1 和 α2\simeq0.5;第 II 组,其中 A⁄⁄\simeq0.017 cm-1 和 α2\simeq0.7,以及第 III 组,其中两个铜离子相互作用。很明显,它们与先前研究的三种含铜蛋白质很好地对应。

A new methodology for creating electroactive components for organic batteries, based on the construction of a molecular platform including stable 3,4-dihydro-1,2,4,5-tetrazin-1(2H)-yl radicals was described. A series of 2-(4-R-1-phenyl)-6-(4-R-2-phenyl)-4-phenyl-3,4-dihydro-1,2,4,5-tetrazin-1(2H)-yls with substituents of various nature was obtained. It was shown that the substituents R-1 in the aromatic ring at position 2 of the tetrazinyl fragment influence the value of the oxidation potential in the radical, but do not influence the value of the reduction potentials, while the substituent R-2 of the aromatic ring at position 6 influence the values of the reduction potentials and practically do not influence oxidation potential values. Based on the obtained electrochemical data, a correlation structure-potential value was revealed for the cathodic and anodic process, with the help of which triarylsubstituted 3,4-dihydro-1,2,4,5-tetrazin-1(2H)-yl radicals with high values of the electrochemical gap were obtained.
