The syntheses and the electrochemical behavior of the monomeric peralkylated hexaamino(1,3)metacyclophane 4, the dimeric dodecaamino(1,3)cyclophane 5a, and the dodecaamino(1,3,5)cyclophane 6 are described. Electrochemical measurements show that the hexaaminobenzene units in 4 and 5a undergo an unusually slow two-electron transfer attributed to the deformation of the rings into bis-cyanine cations when
描述了单体过烷基化的六氨基(1,3)甲基环环烷4,十二聚氨基(1,3)二聚体5a和十二氨基(1,3,5)环庚烯6的合成和电化学行为。电化学测量表明,在4a和5a中的六氨基苯单元经历异常缓慢的两电子转移,这是由于当环氧化为相应的金属离子时,环变形为双花青阳离子。在更多的正电势下,进一步氧化为三,四和六阳离子单元。在二聚体结构中,在(1,3)环烷中看不到环之间的相互作用,但观察到(1,3,5)环烷具有强相互作用。
