由原位生成的2，2 ′-四硫代联苯与GeCl 2·（二氧六环）反应，得到了一种带有3，3 ′，5，5 ′-四叔丁基-2，2 ′-联苯基团的螺锗芴（1）.通过单晶X射线衍射分析和电化学测试研究了1的固态结构和氧化还原行为。空间位阻联苯配体赋予1高氧化还原稳定性和增加的电子亲和力。理论DFT计算证实了实验观察。
A spirogermabifluorene that bears sterically demanding 3,3′,5,5′-tetra(t-butyl)-2,2′-biphenylene groups (1) was obtained from the reaction of in-situ-generated 2,2′-dilithiobiphenylene with GeCl2·(dioxane). The solid-state structure and the redox behavior of 1 were examined by single-crystal X-ray diffraction analysis and electrochemical measurements, respectively. The sterically hindered biphenyl ligands endow 1 with high redox stability and increased electron affinity. The experimental observations were corroborated by theoretical DFT calculations.
