摘要： 用化学方法合成出HMTTeF-TCNQF4,组成比为1.07:1,测定氮1s电子的X射线光电子能谱(XPS),得电荷转移量ρXPS=0.74;测定拉曼光谱,得ρRam=0.75,HMTTeF分子只有失去中心共轭π电子的离子化,而无碲原子失去孤电子的离子化,在固体中存在的价态形式为:([HMTTEF]+0.79+[HMTTeF]00.28·([TCNQF4]-0.79+[TCNQF4]00.21),这与该物质电导率较高的事实相符。

Abstract: The title compound, Hexamethylenetetratellurafulvalene (HMTTeF) and tetrafluo-rotetracyano-p-quinodimethane(TCNQF4) with component ratio between the electron donor and acceptor being 1.07:1, was prepared by the chemical method.The degree of charge transfer of HMTTeF-TCNQF4, determined by X-ray photoelectron spectroscopy of 1s electrons of nitrogen and Raman spectroscopy are:ρxps=0.74 and ρRS=0.75, respectively.The ionization of the conjugate ρ-electron in the compound was found.The form of valence in the compound is: ([HMTTEF]+0.79+[HMTTeF]00.28·([TCNQF4]-0.79+[TCNQF4]00.21).This is consistent with the result of higher electrical conductivity measured.
