摘要： 合成了13个四芳基卟啉锰配离子的TCNQ电荷转移盐[TAPMn][TCNQ]n(TAPH2=α,β,γ,δ-四芳基卟啉;A=C6H5,4-CH3C6H4,4-CH3OC6H4,4-ClC6H4,3-ClC6H4,3-FC6H4,4-(CH3)2NC6H4,2,4-Cl2C6H3;TCNQ=7,7,8,8-四氰基对苯醌二甲烷;n=1,2).通过元素分析、IR、XPS、ESR、磁化率和电导率对其进行了表征.结果表明:这些电荷转移盐分子中存在TCNQ0和TCNQ-,且TCNQ0和TCNQ-之间存在相互作用,部分电荷从[TCNQ]n-向[TAPMn]+转移,导致化合物中的锰表现为混合价态.复合盐的室温电导率在10-7～10-10S·cm-1,属于有机半导体,简单盐的室温电导率小于10-11S·cm-1.

Abstract: Thirteen TCNQ charge transfer salts of tetraarylporphinatomanganese complex ions with the general formula [TAPMn] [TCNQ]n (TAPH2=tetraarylporphyrin; A=C6H5, 4-CH3C6H4, 4-CH3OC6H4, 4-ClC6H4, 3-ClC6H4, 3-FC6H4, 2,4-Cl2C6H3, 4-Me2NC6H4; TCNQ=7,7,8,8-tetracyanoquinodimethane; n=1, 2) have been synthesized and characterized by elementary analyses, IR spectra, X-ray photoelectron spectra, ESRspectra, magnetic susceptibilities and conductivities. The results indicate that there are TCNQ- and TCNQ0 in the molecules of these charge-transfer salts as well as interaction between TCNQ- and TCNQ0. It leads manganese of these compounds to mixed valence state because partial electrons transfer from [TCNQ]n- to [TAPMn]+. The room temperature conductivities of the complex salts are between 10-7 and 10-10S·cm-1, they belong to organic semiconductor. The conductivities of the simple salts are lower than 10-11 S·cm-1 .
