The present article reports on a new and efficient synthetic strategy towards tetracene-bipyridiniums. On the basis of extensive experimental analyses supported by DFT simulations, we report the first observation of a mixed valence complex formed in solution under standard conditions from an unconstrained bis-viologene derivative.

本文报道了一种针对并四苯联吡啶鎓盐的新型高效合成策略。基于密度泛函理论（DFT）模拟支持下的广泛实验分析，我们首次观察到在标准条件下，一种无约束的双紫精衍生物在溶液中形成了混合价态络合物。
