The Study of Formation and Reactions of Polygermyl Ion Radicals

1.观察了全甲基化多锗-四氰乙烯(TCNE)络合物的电荷转移光谱。电荷转移光谱的频率与多锗化合物的电离电位(或化学氧化电位)呈线性关系。结论：1.在温和的条件下，多语种插入TCNE可形成1：1的加合物。在脉冲辐解方法中，使用了两种多原子分子。四氢呋喃(THF)是产生聚锗基阴离子自由基的首选。用于产生聚锗自由基阳离子的分子类型包括烷基卤化物，如CH2Cl2和CHCl3。

1. Charge-transfer spectra of permethylated polygermanes-tetra-cyanoethylene (TCNE) complexes were observed. The frequency of charge-transfer spectra was linearly related to ionization potentials (or chemical oxidation potentials) of the polygermanes. Polygermanes inserted into TCNE to afford 1:1 adducts under mild conditions.2. In the pulse radiolytic method two types of polyatomic molecules are used. For the generation of polygermyl anion radicals, tetrahydrofuran (THF) is preferred. The type of molecules used for generation of polygermyl radical cations comprises alkyl halides such as CH_2Cl_2 and CHCl_3.
