Abstract

A novel triptycene-derived bisparaphenylene-34-crown-10 (1) has been synthesized, and shown to form 1:1 stable complexes with both the paraquat G1.2PF(6) and the cyclobis(paraquat-p-phenylene) G2.4PF(6) in different complexation modes in solution and solid state. Moreover, it was found that both the complexes 1.G1.2PF(6) and 1.G2.4PF(6) were formed by charge transfer interactions, and did not dissociate upon the first one-electron reduction process of the bipyridinium ring.

摘要

一种新型三并苯衍生的双对亚苯基-34-冠-10（1）已被合成，并被证明在溶液和固态中以不同的配位模式与对苯二醌 G1.2PF(6) 和环双（对苯二醌-对亚苯基）G2.4PF(6) 形成 1:1 稳定的配合物。此外，还发现配合物 1.G1.2PF(6) 和 1.G2.4PF(6) 都是通过电荷转移相互作用形成的，并且在联吡啶环的第一次单电子还原过程中不会解离。
