合成了1,5-二(对甲氧基二苯胺)蒽(1)、2,6-二(对甲氧基二苯胺)蒽(2)和9,10-二(对甲氧基二苯胺)蒽(3)三种化合物,对它们的电化学、吸收和发射光谱、光谱电化学以及胺-胺电子耦合开展研究.三种化合物在+0.6~+1.0 V vs Ag/AgCl区域存在两步可逆氧化还原过程,两个氧化还原过程电位差DE在100 mV左右.单电子氧化产物1~(·+)在近红外区域观测到弱价间电荷转移吸收(IVCT),电子耦合常数Vab估算为600 cm~(-1).化合物3~(·+)观测到强IVCT吸收,其Vab估算为1440cm~(-1).单电子氧化产物2~(·+)则没有观测到明显IVCT吸收,表明有机胺在蒽桥基上的取代位置对胺-胺电子耦合程度有重要的影响.
(1), 2,6-bis (p-methoxydiphenylamine) anthracene (2) and 9,10-bis (p-methoxydiphenylamine) anthracene ) Anthracene (3), and their electrochemical, absorption and emission spectra, spectroelectrochemistry and amine-amine electron coupling were studied.The three compounds have two steps in the region of + 0.6 ~ + 1.0 V vs Ag / AgCl Reversible redox process, the potential difference between the two redox processes DE about 100 mV.One-electron oxidation product 1 ~ (· +) in the near-infrared region was observed in the weak charge transfer between charges (IVCT), the electronic coupling constant Vab estimated 600 cm -1, the strong IVCT absorption was observed for the compound 3 ~ (· +), and its Vab was estimated to be 1440 cm -1. No obvious IVCT absorption was observed in 2 · (· +) of the single electron oxidation product, It shows that the substitution position of organic amine on the anthracene bridging group has an important influence on the degree of amine-amine electron coupling.
