胺铜或镍配离子的TCNQ电荷转移盐的合成和物理性质

合成了七个胺铜或镍配离子的TCNQ电荷转移盐ML2]TCNQ]n(TCNQ=7, 7, 8, 8-四氰基对苯二醌二甲烷; n=2, 3;M=Cu, Ni; L=tn, pn, dien, dmtade)。通过元素分析、红外光谱、电子光谱、顺磁共振谱、光电子能谱、磁化率和电导率对这些电荷转移盐进行了表征。结果表明, 这些电荷转移盐分子中存在TCNQ^0和TCNQ^-且TCNQ^0与TCNQ^-之间存在相互作用, 部分电荷从TCNQ]n^2向ML2]^2^+转移, 导致化合物中的金属表现为混合价态。七个样品的室温电导率在10^-^5～10^-^1^0S.cm^-^1, 属于有机半导体, 其导电性主要归结为一维TCNQ分子柱的形成。

Synthesis and physical properties of TCNQ charge-transfer salts of amine copper or nickel complex cations

Seven TCNQ charge-transfer salts of amine copper or nickel complex cations, ML2] TCNQ]n (TCNQ=7, 7, 8, 8-tetracyanoquinodimethane; n=2, 3; M=Cu, Ni; L=tn, pn, dien, dmtade), have been synthesized. These charge-transfer salts have been characterized by elemental analysis, infrared spectrum, electronic spectrum, electron paramagnetic resonance spectrum, XPS, susceptibility and conductivity. The results indicate that there are TCNQ^0 and TCNQ^- in the molecules of these charge-transfer salts as well as interaction between TCNQ^0 and TCNQ^-. The TCNQ]n^2^- to ML2]^2^+. Room temperature conductivities of the seven samples are in 10^-^5～10^-^1^0S.cm^-^1, therefore they belong to organic semiconductor. Their conductivities are mainly attributed to the formation of TCNQ molecular column of one dimension.
