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．Thirteen TCNQ charge transfer salts of tetraarylporphinatomanganese complex ions with the general formula TAPMn TCNQ n (TAPH 2=tetraarylporphyrin; A=C 6H 5, 4 CH 3C 6H 4, 4 CH 3OC 6H 4, 4 ClC 6H 4, 3 ClC 6H 4, 3 FC 6H 4, 2,4 Cl 2C 6H 3, 4 Me 2NC 6H 4; TCNQ =7,7,8,8 tetracyanoquinodimethane; n =1, 2) have been synthesized and characterized by elementary analyses, IR spectra, X ray photoelectron spectra, ESR spectra, magnetic susceptibilities and conductivities. The results indicate that there are TCNQ - and TCNQ 0 in the molecules of these charge transfer salts as well as interaction between TCNQ - and TCNQ 0. 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 -10 S\5cm -1 , they belong to organic semiconductor. The conductivities of the simple salts are lower than 10 -11 S\5cm -1 .
